Your body is only as strong as the weakest link so small muscles in your forearms, hands and wrists play an essential role in any exercise that involves lifting weights. These angled springs allow for graded resistance to be used to train for hand strength and grip endurance.

Train your grip strength during your 'down time' rather than during a full workout because these grip trainers are designed to challenge and fatigue your grip temporarily which is not what you want in the middle of a full body training session. Your 'grip muscles' are multi task muscles so ensure that you combine moving squeezes with static holds.
