Pull-up
Hang from a bar with the palms facing away, grip just wider than the shoulders, ribs down, legs quiet.

- 1Start by pulling the shoulders down, away from the ears.
- 2Drive the elbows toward the hips until the chin clears the bar.
- 3Lower to a full hang without shrugging at the bottom.
Easy to miss: Kipping, or stopping short so the arms never straighten.
Muscles
Copper on the figure is a prime mover. The softer tone helps.
