Back squat

Bar on the upper back, feet about shoulder-width, toes slightly out.

Back squat
  1. 1Break at the hips and knees together. Sit down between the heels.
  2. 2Knees track over the toes. Parallel is deep enough if the position holds.
  3. 3Drive the floor away and keep the chest from collapsing.

Easy to miss: Knees caving in, or stopping so high the quads barely work.

Muscles

Copper on the figure is a prime mover. The softer tone helps.
