A solid silicone ring for the hands, fingers and forearms, rated from 88.2 to 110.2 lbs of resistance. Squeeze, hold, release - that is the whole method, and it works as well at a desk as it does on a gym floor.
The surface is textured so the ring does not skid out of a sweaty palm, and it measures roughly 6.00 inches / 15.24 cm across, which suits most hand sizes. Colour coffee black.
Grip strength carries straight over into pulling work, climbing and anything that involves holding on to something heavy for longer. It also earns its keep as a quiet fidget during a long call, and as part of a gentle routine when the forearms are tight.
