Peak Performance with Style - The All-New Powerball Metal Grip Strengtheners have reinforced stainless steel springs with a matt black anodization finish. Each weight resistance is distinguished by its own beautifully coloured handle with a diamond etched matrix pattern for extra grip ensuring that these grippers look good sitting on your desk as they wait for your next pulverising forearm and grip strength workout session.
X-Strong Black Resistance (250lbs) - We classify the resistance level of our black PowerGripper as X-STRONG (250lbs / 113kg). This is an advanced resistance level, suitable for experienced trainers and athletes and is typically one to be worked up to with our lower resistance models beforehand (unless you're already blessed with superlative forearm and grip strength, in which case dive right in!).
Training Guide - Each Gripper comes with its own training guide to help maximise your strengthening and rehabilitation results. Choose from a variety of holding positions in the hand, using some or all fingers. Decide to close and hold for 15-30 seconds or simply to pulse from opened to closed over the course of a 1-2 minute session. There are an endless variety of exercises which you can perform with this simple but highly effective upper limb strengthening instrument that will produce big results in forearm and grip power in a very short time.Gold standard warranty - Lifetime manufacturer’s warranty included.
