BACK
Chin Up
The chin-up is a bodyweight pull that hammers the back while giving the biceps plenty of work. It's essentially a pull-up done with an underhand grip, which many people find a touch friendlier to start with. It's an excellent way to get comfortable on the bar and build real strength and muscle.

- 3
