I want to build strength in my wrists/arms/shoulders - which ball should I choose?

We currently offer 6 individual Powerball® models on the site. Each generates smooth, progressive, 100% non-impact resistance and are suitable for building strength in the fingers, hands, wrists, arms and shoulders - with the exception of the 450 Diablo™ lightweight model which is recommended for rehabilitation or high speed spinning purposes only.

However, for specific strength training purposes, the 350 Diablo™ model sits head and shoulders above all the other models in the range in that it generates significantly more resistance as a result of its heavier, solid zinc rotor engine and chromed stainless steel shell. 350 Diablo™ develops 18.6kg (41.45lbs) of inertial resistance/force at 10,000rpm as compared to 11.3kg developed by the polycarbonate based 280™ models.

Additionally, and despite its considerably higher power output, Diablo's shell circumference is approximately 10% smaller in size when compared to the 280™ models, allowing it to fit better into the hand, resulting in a firmer grip and consequently a higher spin speed overall, which in turn helps develop even more muscular strength.

Which is the most powerful model?

The most powerful model in the current range is the 350 Diablo Pro™. With a solid zinc rotor encased in a chrome finished stainless steel shell, 350 Diablo™ is capable of generating almost 30kg (60lbs+) of inertial resistance and will develop 18.6kg (41lbs+) at just 10,000rpm. Despite it's immense power, 350 Diablo™ is also approximately 10% smaller than the other models, allowing it to fit really tightly into the hand for maximum grip-a-bility.

What is the difference between Powerball® and the cheap copies?

Powerball® is a tuned, precision strengthening and rehabilitation instrument which has been hand assembled using premium quality materials and features an internal rotor on a hardened stainless steel axle which has been so finely and precisely balanced using advanced computerised technology that it can reach speeds in excess of 18,000rpm without vibration of any description.

Because of the success we've achieved around the globe with the Powerball® product range, we've attracted a large variety of imitation gyro products, most of which originate from China. Many of these bear a confusing resemblance to the genuine products sold on this website but fall far short in terms of build; quality of materials used; performance; reliability and overall product safety resulting in;

  • Unbalanced rotors which may vibrate unpleasantly during use, causing impact and soft tissue damage to the user;
  • Top speeds which may be limited to less than 10,000 - 12,000rpm;
  • Self destruction of products during use, emitting dangerous, sharp debris;
  • Use of iron axles which deform if the unit is dropped or suffers shock, causing significant and irreparable vibration thereafter

Any Powerball® you'll purchase on this website is;

  • Hand built and supplied with a lifetime product warranty;
  • Certified to spin to a minimum of 18,000rpm with zero vibration;
  • Manufactured from only the highest quality materials;
  • Contain polished stainless steel rotor axles for long life, vibration free performance;


Additionally, several models in the range feature patented Autostart™ mechanisms and drop resistant shells with reversible inner tracks to facilitate ease of use and up to 400% longer product usability - don't settle for anything less.

What age should I be to use Powerball®?

It is recommended that Powerball® should not be used by those under the age of 12 years without adult supervision (more as a general precaution rather than an actual insistence) to highlight the simple fact that these products can generate significant resistance (gyroscopic inertia), most of which is applied directly to the wrist/arm. In younger persons, active bone development is still in progress and may be adversely affected by such potential forces, leading to possible damage in the arm or wrist as a result.

(Powerball® produces localised resistance in a completely different way to conventional free weight - isotonic exercise workouts).

However, and given that Powerball® will only generate such resistance which is directly proportional at all times to the efforts expended by the user, it is highly unlikely that any young individual will ever cause himself/herself harm through the use of this product - nonetheless it remains prudent that caution be observed and that our younger users be fully aware of the potential for overuse that may arise as a result of the high power outputs of these highly addictive products.

Used in moderation, Powerball® will be an extremely beneficial tool for a budding young sportsperson (or aspiring musician... or fitness enthusiast... or martial arts devotee... or gymnast... or....) and will not cause any harm; indeed, we receive many gracious testimonials each week from parents who are simply delighted with the effect that the shiny sphere has had on their particular offspring’s sporting achievements. The rules are therefore simple;

  • Never exceed your own abilities with Powerball® and;
  • Slow speeds for gentle rehabilitation / high speeds for muscle building power where appropriate

How fast should I spin?

Powerball® is fast...(very fast)...and in this case speed really does equal force - the faster the rotor engine spins inside the shell sphere, the more gyroscopic inertial resistance it's generating - force that's being levied directly upon the arms and wrists in particular.

As one of the very best upper limb strengthening and rehabilitation devices available in the world today, Powerball® will be equally at home with someone nursing an arm or wrist injury as it will in the hand of someone trying to build large, powerful forearms and grip strength - yet both users will have very different requirements and both will therefore need to be spinning at very different speeds.

The general rule is:

  • Slow to moderate spin speeds for longer periods (3-15 minutes) = soothing rehabilitation
  • Fast, high speed bursts for short periods (20 - 60 seconds) = muscle building, toning & strengthening

Age; physical condition; muscle endurance ability; whether the limb is injured or 100% healthy and strong; whether it's suffering from fatigue as a result of over-training - each of these factors will have a direct input on what your 'ideal' spin speed will be and each will change week by week, so what is an ideal speed for you today will be perhaps 1500rpm off the pace 7 days later. Always listen to your body and, like any exercise you'd perform in your local gym, always remain within your own physical abilities - spinning too hard as a beginner or without properly warming up the muscles beforehand is similar to lifting a dumbbell that's simply too heavy - you could cause a soft tissue strain.

How long should I spin?

Like the question 'how fast should I spin' above, the answer to this relates directly to the physical condition of the user and whether they are using Powerball® to build strength or to rehabilitate an injured limb. With Powerball®, faster spin speeds generate higher inertial resistance from the sphere and require more strength and muscle endurance to maintain control.

Powerball® is an isometric exercise device and the resistance generated is 'always on' while the rotor is spinning - there is no let up. It has been scientifically proven that isometric exercise engages a higher percentage of muscle fibers than regular isotonic (weight) training and produces measurable results within a far shorter time frame.

As a result, someone with a case of wrist tendonitis could sit and gently spin Powerball® at a speed of 5000rpm for the entire 45 minute duration of their favourite TV show, bringing soothing relief through enhanced blood flow in the inflamed tendon tissue, while a seasoned gym warrior who had never experienced Powerball before would likely struggle to maintain a speed of 11,000rpm for a mere 30 seconds while their forearm flexor and extensor muscles burned like never before - your ideal Powerball® speed & spin duration is a totally personal affair that will depend on age; physical condition; muscle endurance ability; whether the limb is injured or 100% healthy and strong; whether it's suffering from fatigue as a result of over-training and you'll learn this over a period of 5-6 days of using the ball while your muscles acclimatise to what is a unique, efficient and highly effective training solution.

Do I need to grip firmly when I spin?

Enormous forces are built up inside the sphere at high speed and the ball is always fighting hard to oppose your efforts to spin that inner rotor - therefore it is always recommended that you maintain a firm, tight grip on your Powerball® during use to ensure you maintain full control.

Doing so also ensures minimum wear on the internal mechanism and ensures a long, maintenance free product life - in fact, treat it properly while you spin and your Powerball® will still be spinning smoothly and going strong 15 years from now. As will your wrists and arms. (In fact, we often receive correspondence from customers who have purchased Powerballs® from us as far back as 2001/2002; a testimony to just how useful you are going to find this unique product).

What happens if I switch rotor spin direction in the middle of a spin?

Once the rotor is spinning at a sufficient pace, it comes under the effect of what's known as gyroscopic precession where it effectively becomes suspended inside the sphere, allowing it switch between clockwise and anticlockwise rotation with just a flick of your wrist.

Does this cause damage to the internal mechanism? Well, if the transition is made smoothly, at a moderate speed and by someone using proper spin technique then no... but, like trying to change gears in your car without pushing the clutch down properly, some small wear will likely occur over time if you attempt to change direction at too high a spin speed and too often so always try to perform nice, fluid clockwise - anticlockwise transitions as you spin and everything will be just fine.

Can I use Powerball® in both hands?

Most people will have a dominant hand and this, by nature, usually tends to be the one which most often suffers from those repetitive strain injuries that Powerball® loves to rehabilitate.

As a result, you might actually find yourself exercising / rehabilitating with Powerball® in your dominant hand almost to the exclusion of the other limb as you try to moderate a tennis elbow or wrist tendonitis issue and this is something we'd encourage you to try and avoid if possible; prevention is always better than cure and even if it's only 'a 1 minute spin in the left hand versus 5 minutes in the right' try to make sure you always include at least a quick session in the non-dominant hand each time you spin to ensure a good balance in both strength and co-ordination across both.

Why does the rotor make a slapping noise as it spins?

Building progressive speed on your Powerball® demands proper technique to ensure that your wrist rotation is correctly matched and synched to the spinning rotor at all times.

While learning the correct technique at the very beginning, some users will either attempt to rotate their wrists too quickly or, make the circumference of their turning circles too small; this results in them running out of sync with the spinning rotor and causes it to 'slap' or clack noisily in the shell every few seconds - synchronising your wrist rotation speed so that it fully aligns with the rotor speed will solve this immediately and see your Powerball® spin quickly soar to 10,000rpm+.

From experience, you will see that a good, sharp pull on the starting cord or winding the rotor back 2-3 turns on your Powerball® Autostart™ and releasing will activate the rotor to approximately 2500/3000rpm - this is the ideal Powerball® starting speed.

From that point, you'll need to begin ‘agitating’ the rotor by turning your wrist at a slow, steady pace so that it manages to sync perfectly with the spinning rotor inside the shell sphere, which in turn helps to both sustain and build its speed.

This is actually easier to do than it sounds and is just like riding a bicycle; once you've 'got it' that first time, and felt the perfect resistance from Powerball®, you'll 'get it' every time thereafter and won't need to think about it anymore, it'll all happen naturally.

If you're a beginner with Powerball®, we always recommend starting off with wide, lazy wrist turns, such as if you were stirring a pot, whisking eggs or swirling ice cubes in a glass - each turn about 5/6" in diameter and between 1 to 2 turns each second, no faster.

It is all about feel - you will immediately know that you are at the correct speed as you will begin to feel a resistance to your wrist rotation efforts (when you are out of sync, there will be no resistance, the rotor may ‘slap’ around noisily inside the sphere and it will feel as if you are simply turning your hand around the wrist joint - when in sync however, there will be a pleasant, soothing opposition to your efforts and Powerball® will suddenly feel much heavier in your hand as it fights against your efforts to build that rotor speed).

Once you feel this resistance (otherwise known as gyroscopic Inertia), slowly begin to increase the speed of your wrist rotations.

NOTE: it is important that ONLY the wrist rotates - your arm must remain steady, fixed and in the one position (unless you are specifically following one of our recommended exercise video programs where some arm movement is required) - doing so will serve to increase the actual speed at which the rotor is spinning which, in turn, will increase the resistance being inflicted on your hand/wrist/arm.

Once again, if you are trying to turn your wrist too fast while at these initial starting speeds or, if your turning circles are too small at the beginning, you will hear (and feel) the rotor slapping noisily inside the sphere - again, if this happens, simply slow the speed of your turns or increase the circumference of each turn; this will immediately help to bring you back in sync with the spinning rotor and the speed will build proportionally once again.

Maintenance

Proper maintenance of Powerball®

The latest range of Powerball® models are smoothest, fastest gyros we've ever produced and have been manufactured from premium materials to ensure high performance and ongoing benefit for the fingers, hands, wrists and arms.

While your Powerball® has been designed to be maintenance free, you'll find that opening it from time to time and giving the surfaces of the internal components a quick wipe down with a clean, dry cloth will be beneficial to its overall performance and keep it running smoothly and quietly.

Details on how to open your Powerball® can be found as follows:
Opening 280Hz model range (280 Pro, Autostart Classic, Pro, Fusion Pro) • Opening Diablo model range (350Hz & 450Hz)

My cord is stuck in the ball

The cord will sometimes become stuck fast around the rotor axle if a) it is either not wrapped tightly around the rotor surface before being pulled or b) it is not pulled STRAIGHT OUT from the ball during the starting procedure (note: pulling at an angle during the starting process may increase the possibility of the cord getting caught inside the mechanism).

You can learn the correct technique for starting your cord-activated Powerball® by watching this video:


Should the cord have gotten stuck in the mechanism however, then please follow this simple procedure to release it again;

280™ Pro™ models

  1. Making sure your hands/fingers are clean and 100% oil free, remove the grip band from your Powerball®.
  2. Obtain a small Philips (cross head) screw driver and remove the three small silver screws that you'll see spread evenly around the circumference of the ball shell.
  3. You'll note that there is a narrow groove - about 1.2mm wide - running entirely around the middle circumference of the ball. You'll also see that there are 6 little lock-tabs which anchor the top shell half to the bottom shell half.
  4. Obtain a small coin (a 5 cent euro coin is absolutely perfect) or the blade of a flat head screw driver and insert it into the grove directly beneath any of these 6 lock-tabs and then press gently downward on the coin/screwdriver; this will lift the shell half outward and disengage it from the securing tab.
  5. Repeat this process for all 6 tabs until the two shell halves are full disengaged and can be lifted apart to expose the rotor and trapped cord inside.
  6. Examine the direction in which the cord has been wound around the axle and rotate the rotor in the opposite direction - this will slowly and gently unwind the trapped cord without any damage.
  7. Once the cord has been removed, use the opportunity to gently blow out any plastic dust that may have accumulated on the internal mechanisms of your Powerball®.
  8. Correctly reposition all internal parts and snap the two shell halves back together, ensuring all 6 tabs have locked correctly into their respective anchors on the opposite shell half.
  9. Reinstall the 3 screws.
  10. Reposition the grip band - you are ready to spin once again.

Diablo™ 350Hz™ & 450Hz™ models



  1. Making sure your hands/fingers are clean and 100% oil free, remove the grip band from your Powerball®.
  2. Examine the shell circumference of the ball; you'll note that there are 6 lock-tabs securing the two shell halves together.
  3. Diablo shells are manufactured from light stainless steel and are quite flexible in their nature; the object here is to put enough pressure directly on the shell circumference so that the lock tabs disengage from each other - one by one - and the two shell halves pop apart.

    This is done as follows;
    • Observe the rotor and become aware of exactly where the axle tips are likely to be positioned inside the shell. The rotor axle is a hardened stainless steel rod about 65mm in length which runs directly through the center of the rotor with its tips extending out about 10mm on each side and supporting the rotor inside the ball - you'll quickly be able to establish exactly where these might be located by giving the rotor a quick spin.
    • Because we will be pressing downward on the flexible shell, it is of utmost importance that the rotor axle is NOT pointing directly upward at the exact point where you will be pushing down (ie, it's NOT standing perpendicular to the table surface that the ball is resting upon during this entire process). Were it to do so, it will a) act as a solid support and prevent the shell from flexing against your efforts and b) you'll actually risk bending/deforming the rotor axle irreparably with the downward pressure you'll be applying.
    • Therefore, ensure that the axle is close to being PARALLEL to the table surface on which you've placed the ball before starting to press down on the shell (it doesn't have to be exactly parallel, but it must NOT be perpendicular at any point during this process)
    • Begin to apply firm pressure on the shell at this stage - directly upon its circumference - if you do this correctly, you'll feel the shell begin to yield and feel/hear a slight 'pop' as the first lock-tab disengages.
    • At this point, rotate the ball by approximately 90 degrees (ie; move it from a 12 o'clock position to a 3 o'clock position) - feel free to adjust the rotor inside to ensure that the axle hasn't become perpendicular to the table surface as a result of moving the ball like this and press firmly downward on the shell circumference once again.
    • Repeat this process as necessary, rotating the ball by a quarter turn before each downward press and ensuring at all times that the rotor never becomes perpendicular to the table surface.
    • With each press, you should be noting the shell halves disengaging further apart, right up to the point where you'll find it easy to pull them apart with your fingers.
  4. Part the two shell halves and observe the direction in which the cord is wrapped around the rotor axle.
  5. Wind the rotor gently backward in the opposite direction - this will yield the cord slowly and steadily from the axle without damage.
  6. Once the cord has been removed, use the opportunity to gently blow out any plastic dust that may have accumulated on the internal mechanisms of your Powerball®.
  7. Correctly reposition all internal parts and observe that the two shell halves are arranged so that the 6 lock tabs on one shell half are aligned directly opposite the respective anchor holes in the other shell half.
  8. Snap the two shell halves back together and ensure all 6 tabs have engaged correctly (because it's a stainless steel shell, it will be necessary to apply firm pressure on the two shell halves to ensure that these lock-tabs lock together fully).
  9. Reposition the grip band - you are ready to spin once again.


Note:
Never, ever oil the inside of your Powerball®. To do so will immediately destroy the frictional relationship between the rotor and the shell and ensure that it will no longer spin. You many also find that your Powerball feels a little different if you've cleaned the internal mechanism - this is normal as you've slightly altered the frictional relationship between rotor and shell. However, you'll find that this will quickly build back to normal expected resistance levels following a few minutes fast spinning.

Can I replace the batteries in the counter?

All counters in the current Powerball® product range receive their power by induction directly from the spinning rotor - so it's "human power" all the way and no batteries required!

I have oiled my Powerball®

Your Powerball® is a high precision instrument which operates around the perfect frictional relationship between the rotor support band (a special plastic ring which supports the rotor) and the circular platform inside the shell on which that rotor support band sits. The materials used on the support band and shell have been specially chosen to ensure a perfect frictional harmony which converts your wrist action into pure rotor speed.

One drop of oil however... just one, single, tiny drop... placed anywhere - either on the internal shell platform or on the support band - will be sufficient to completely destroy that perfect frictional harmony and ensure that the rotor flops around lifelessly inside the shell, unable to respond to even the most perfectly synched wrist turn. Your Powerball® will be well and truly...dead!

The solution:

  1. Open Powerball® (please follow these instructions) and dismantle it to base component level.
  2. Get some pure alcohol and start cleaning each and every component surface, paying particular attention to the entire rotor support ring and the actual surface areas on the inner sphere on which the rotor support band sits.
  3. Make sure you use a pure, NON SOLVENT solution - ie, DO NOT use a nail varnish remover or similar, otherwise you will risk melting the surface areas.
  4. Ideally you should use a pure alcohol to ensure that it evaporates fully after the process and leaves no residue behind.
  5. Once cleaned, rub down all surfaces once again with a clean, dry cloth to ensure that any potential residue has been fully removed and then reassemble Powerball®.
  6. Once the oil has been removed in this manner, the prior frictional relationship will be fully restored and Powerball® should spin smoothly as before.


NOTE: We recommend that you also observe caution against using your Powerball® anytime you're wearing hand cream. There is a potential for some of the cream to find its way onto the rotor surface during the starting process, moving from there onto the rotor support band as a result of the high speed of the rotor during use and with obvious consequences for the friction thereafter. If you're wondering why your perfectly operating Powerball® has suddenly stopped working the next day, you might want to give consideration to this as a possible cause and get the bottle of pure alcohol and tissues ready..)

So we repeat...no oil...ever!

I've lost the starting cord, what do I do now?

Please click here and fill in the details on the form - we’ll issue you a replacement pair of cords once you have given us the required information.

While you are waiting for your new cords however, please note the following details which should have you spinning again in minutes:

  • Please go and find a piece of knitting wool about 45 centimeters long.
  • It should be light grade wool and you'll need to tie a knot in both ends.
  • Then, tie a second knot at each end which exactly covers the first knot to ‘bulk’ it up.
  • Get a match and burn these ‘knotted’ ends so that there is a small, hard tip on each end of the cord.
  • This tip should now be about 3-4mm in length and should be hard and large enough to gain purchase in the hole in the rotor (where the proper cord will eventually fit).
  • If the tip is still a little too flexible, then get a little bit of super glue and apply to the end, letting it set. This will definitely make it hard enough to allow you start the ball as you would with the proper cord.

Likewise, if the tips have come off the original cord, you can use this technique to build up the ends of the [cord] to allow them grip the rotor properly during the starting procedure.

The grip band comes off my Powerball® when I am spinning really fast

Powerball® is capable of developing significant force and inertial resistance as it spins and demands considerable grip strength to keep it firmly seated in the hand at higher speeds. To help facilitate this, each Powerball® is fitted with a special, highly tactile silicone grip band which stretches fully around the shell circumference and makes it easier to hold during the spin.

However, when used over an extended period of time, sweat and oils from your hand may sometimes permeate the band and cause it to lose its tactile grip over the shell surface, resulting in it becoming slightly loose and moving up/down from the circumference of your Powerball® as you spin, particularly at higher speeds.

If this does occur on your Powerball® then the simple solution is to remove the band and put it into the washing machine with the next wash or into a basin of moderately hot water with some washing up liquid - this will shrink the band fractionally and ensure that the sweat/oils are removed, allowing it to assume the sticky/tactile characteristic it had when new.

(Remember, if there are oils on the grip band, there will also be oil on the shell surface too, so please ensure you use this opportunity to also give the shell surface a quick clean with a baby wipe (or similar) and dry immediately with a paper towel).

How to open Powerball®

280 Pro models

  1. Making sure your hands/fingers are clean and 100% oil free, remove the grip band from your Powerball®.
  2. Obtain a small Philips (cross head) screw driver and remove the three small silver screws that you'll see spread evenly around the circumference of your Powerball® shell.
  3. You'll note that there is a narrow groove - about 1.2mm wide - running entirely around the middle circumference of the ball. You'll also see that there are 6 little lock-tabs which anchor the top shell half to the bottom shell half.

  5. Repeat this process for all 6 tabs until the two shell halves are full disengaged and can be lifted apart to expose the rotor other internal components.
  6. Once open, use the opportunity to gently blow out any plastic dust that may have accumulated on the internal mechanisms of your Powerball®.
  7. To close; correctly reposition all internal parts and snap the two shell halves back together, ensuring all 6 tabs have locked correctly into their respective anchors on the opposite shell half.
  8. Reinstall the 3 screws.
  9. Reposition the grip band - you are ready to spin once again.


350 Diablo™ & 450 Diablo™ models
  • Making sure your hands/fingers are clean and 100% oil free, remove the grip band from your Powerball®.

  • Rehabilitation

    I have a wrist/elbow/shoulder injury - which Powerball® should I choose?

    We currently offer 6 individual Powerball® models on the site. Each generates smooth, progressive, 100% non-impact resistance and all are suitable for rehabilitation of any finger/hand/wrist/arm/shoulder based injury that you may be experiencing.

    However, please be aware that the 350 Diablo™ model listed on the site is manufactured with a stainless steel shell and heavy, solid zinc rotor engine capable of generating considerably more power than the other models in the range while spinning at similar speeds. As such therefore, while it can still be used at lower speeds to help rehabilitate any upper limb related issues, it tends to be more suited to those customers seeking muscle building/strengthening as a result of the higher inertial resistance that it can generate.

    For rehabilitation purposes therefore, we would specifically recommend any of the three Powerball® Autostart™ models listed on the site. Autostart means simple, fuss free starts every time; you simply wind back the rotor 2-3 turns and release to spin - no starting cords required. This model range can be operated with a single hand, which is a significant advantage to anyone suffering from limited mobility in their arm. All Powerball& Autostart™ models are also fully drop resistant - a feature that our customers suffering from weak grip certainly find useful.

    By means of quick reference, each of the 4 polycarbonate 280™ models generate approximately 11kg of resistance at 10,000rpm while 350 Diablo™ produces 18.6kg at 10,000rpm, despite weighing less than 1kg when static.

    Will the repetitive movement required to spin Powerball® cause RSI?

    There is a substantial difference in characteristic between the repetitive movement in the upper limb that leads to RSI based conditions and the repetitive movement required to spin Powerball®.

    Typically, RSI conditions in the upper limbs are brought on either by;

    a) Thousands of repetitive, fine, low impact limb movements, carried out for multiple hours per day, several days each week. For example; typing, operating a computer mouse, video gaming, writing, knitting, gardening, assembly line working, etc.

    or;

    b) Repeating identical high impact tasks multiple times each day (over-use) combined with excessive force applied from awkward position and/or with poor limb posture. For example; mechanics using wrenches, driving for hours each day with wrists bent in un-natural angles, meat boners, machine operators, etc

    One of the defining factors in most of the above tasks is that the body on the whole tends to remain sedentary - often for hours at a time - during these activities. That is; the limb may be moving continuously on a local level during the course of the day while carrying out the particular activity, but the body itself tends to remain seated and relatively immobile, with limited heart activity combined to limited overall limb movement.

    This in turn leads to sluggish or slower blood flow throughout the body; blood brings oxygen and collagen enriching nutrients to your muscles, ligaments and tendons, both of which help to keep the tissue supple and flexible and enable the limb to function efficiently as you go about your daily tasks.

    Reduce that vital, lubricating blood flow while performing those repetitive or strenuous daily tasks therefore and all manner of things begin to happen under the skin;

    The forearm muscles (flexor, extensor) literally begin to dry up (lose their suppleness and natural ability to stretch); microscopic tearing begins to appear on the muscle tissue surface, ultimately causing knots; the muscles themselves begin to shorten in length (injured muscle tissue tends to contract) putting pressure on the tendons connecting them to the bone at the elbow and wrist joints. And synovial fluid - the slippery liquid which lubricates the joints and inner walls of the sheaths surrounding the tendons all o ver the body - that remains in a highly viscous state (thick like the oil in your car when you start it on a cold winter morning) and makes it difficult for the tendons inside to slide and glide freely, causing excess friction.

    The sum total of which results in growing inflammation, eventual muscle pain and overall reduced range of joint motion (RSI).

    Using Powerball®, on the other hand, has the exact opposite effect;

    The smooth, progressive, 100% non-impact resistance produced by a spinning Powerball® is directed across the entire muscle range of the upper limb, from finger to shoulder. Unlike the tasks listed above, all of which actually contribute to RSI based conditions, using Powerball® is a form of isometric exercise and, as with any form of exercise, blood flow through the tissue is changed dramatically, flowing at anything up to 15 times more than it might otherwise do through resting muscles (when resting, only 20-25% of the capillaries are open, but during exercise, 100% of the muscle capillaries are open).

    And this is all good news for the upper limbs and, in particular, the tendons connecting the muscles to the elbow and wrist joints. Tendons are made primarily of collagen and nothing helps repair and rehabilitate damaged or inflamed collagen tissue more than nutrient and oxygen rich blood. A healthy muscle tends to stretch and lengthen easily by its very nature and will do so freely once the tissue is filled with warm, viscous blood. And longer, supple muscles in turn help to put less pressure on the tendons which anchor them to the joints, ensuring that the whole limb is more accommodating to those repetitive movements that are so prevalent in our lives today, both in work and during leisure time.

    Blood flow is stimulated, synovial fluid production increases, tissue becomes oxygenated, muscles become supple and stretch more easily, inflammation in the tendons reduces, range of motion in the joint increases... and all of this can happen with just one 3 minute spin.

    NOTE: While 100% non-impact in nature, Powerball® is nonetheless capable of generating substantial resistance/force if used at high speeds, all of which can overload and further stress injured/recovering muscle tissue. Therefore, for the purposes of any recovery/rehabilitation, we ALWAYS recommend long, slow to moderate spins (3-15 minutes in duration at no more than 6000rpm) as opposed to short, fast spins (less than 1 minute at 8,000 - 10,000rpm and above). Doing so will produce rhythmic, gentle resistance from your Powerball with all of the rehabilitative benefits listed above and ensure prompt recovery of the damaged tissue.

    Purchase

    I want to make a group purchase of 10+ balls, can I have a discount?

    Yes, it's one of the world's most effective rehabilitation devices for the hands, wrists and arms beloved of physios around the world. Yes, it's a device which will build extraordinary strength in the forearm flexor and extensor muscles. But what you probably won't realise until you actually feel a live Powerball® spinning in your hand for the first time is just how absolutely addictive it is to use as that exercise / rehabilitation device and how everyone you hand it to for a quick spin will want one too. Rehabilitating a tennis elbow condition or broken wrist isn't meant to be fun but this comes as close as it gets to actually making therapy enjoyable.

    If your Powerball® has captivated friends, relatives and work colleagues, there is a strong chance they'll want to purchase one of their own and so we offer the opportunity to make a group purchase of 10 or more units at a substantial discount to the normal product RRPs. If this is something that you might wish to do, simply fill out your name, address and email details here, along with the models you're looking to purchase and we'll revert with a price, including shipping to have any 10 piece+ order delivered to your door.
