For almost all the exercises performed in the gym, a strong grip is of upmost importance. It is true that we are strengthening the grip almost unconsciously while lifting the Olympic barbell, performing exercises on the bar… But what if an interesting exercise existed just to strengthen grip and grip-related muscle groups in the arms?You are already familiar with our Cannonball Grips, and now we are presenting them in the form of a cylinder. They are easy to install, are very durable and present an incredible challenge to your grip! The lifts become harder, the farmer walk exercise “more fun,” and the effects are similar to the effects of climbing.
