Pull-Ups

Start: using an overhand grip, grab on to a chin-up bar with your hands spaced wider than shoulder-width apart. Hang from the bar with your arms fully extended and your chest high while exaggerating the arch in your lower back.

Move: pull yourself up by squeezing your shoulder blades together and contracting your lats until your chin passes the bar. Hold the contraction at the top for a second before slowly lowering yourself back to the starting position.
