Bang Out a Chin-Up
If you avoid chin-ups, you may be missing out on a time-efficient way to build strength in your core, back, shoulders and arms – a surefire way to sculpt your upper body in one exercise! If you find it daunting, start slow with two or three reps. Use a bench so there is less distance from the floor, or practice on a Smith Machine. Once you master the chin-up, add to the number of reps. And then move on to the big daddy move of them all; the pull-up. All you have to do is change the grip from underhand to overhand and get to work.
