Chin Up.

Make every rep count.

1. 01

   Grab the bar with an underhand (supinated) grip, hands about shoulder-width apart.

2. 02

   Take a deep breath, squeeze your glutes and brace your abs to keep your body tight. Start by pulling your shoulders down and back (depress the shoulder blades) so you’re not shrugging.

3. 03

   Initiate the pull by driving your elbows straight down toward the floor and engaging your lats—avoid swinging or kicking.

4. 04

   Continue until your chin reaches the bar and your back feels fully contracted.

5. 05

   Lower under control to a full hang (or just short if your shoulders bother you), keeping tension and posture, then repeat for the prescribed reps.
