Left-Turn 3 : It's the international benchmark of a world-class grip. Use it to train for certification on the CoC No. 3.Most people who train with grippers think they feel fine in both hands, but if you think your left hand is getting short shrift, a Left-Turn gripper might be for you: it's tailor-made for lefties.Left-Turn grippers are the mirror image of Captains of Crush grippers, so if your trusty gripper doesn't feel quite the same in your left hand as in your right, grab an IronMind Left-Turn gripper and give it a squeeze.P.S. Just as lefties have been using CoC grippers with both hands for decades and getting stronger for their efforts, you can put your right hand through the paces with a Left-Turn gripper, too!
