Why: “You’ll build a grip of steel,” says Kemp. “This exercise reaps more benefits than just working your back muscles.” While the back strength benefits of another pull-up variation are obvious, your grip can be a limiting factor in other major lifts like your deadlift, for example. Double up your gains by targeting both in this exercise to build size and strength, but also build a vice-like hold that will allow you to add an extra kilo to almost every other exercise you do in the gym.
