The Gainworks PowerGRIP is an ergonomically designed forearm gripper designed to maximise grip strength and forearm muscle activation.

Tested with an EMG device, the PowerGRIP shows 63% more muscle activation over standard grippers in the Palmaris Longus and Flexor Carpi Radialis muscles.

It is fully adjustable from 5kg resistance up to 165kg resistance.

Made from a hardy, heavy-duty premium material with an industrial heavy duty spring, this device is built to last a lifetime.
