Squat to Box

Constraint-based squat using a box or bench to control depth and reinforce proper lumbopelvic mechanics. The box acts as external feedback to limit excessive lumbar motion, improve hip contribution, and reduce anterior chain dominance during the squat pattern.

Execution

1Stand facing away from a box or bench set at knee height or slightly above.
2Feet shoulder-width apart, toes slightly turned out as needed.
3Set ribs down and pelvis neutral; brace lightly before initiating the movement.
4Sit the hips back and down toward the box, maintaining a neutral spine.
5Lightly touch the box without fully relaxing.
6Drive through mid-foot and heels to stand, extending hips first.
72–4 sets of 6–10 controlled repetitions.

Cues

Hips back and down, not straight down
Stay stacked: ribs over pelvis
Control the descent, don't drop onto the box
Stand up by pushing the floor away

Common Errors

Relaxing completely on the box (losing tension)
Lumbar flexion or excessive posterior pelvic tilt at the bottom
Anterior knee dominance with minimal hip contribution
Rib flare or lumbar extension during ascent

Progressions

1Higher box -> lower box
2Pause 2–3 seconds on the box while maintaining tension
3Goblet-loaded squat to box
4Remove box and progress to free squat when control is consistent
