Barbell Box Squat
Description
The barbell box squat is a powerlifting squat variation where you sit your hips back to a box at the bottom of each squat, then explode back up. The box ensures consistent depth, teaches sitting back into the squat, and builds explosive concentric strength. Westside Barbell popularized it as a foundational training tool.

Barbell Box Squat Instructions
- Place a sturdy box (or stack of plates) directly behind you at the appropriate squat depth — typically just below parallel.
- Set a barbell at upper-back height in a power rack. Step under and place it across your upper traps. Unrack and step back.
- Stand directly in front of the box with feet shoulder-width apart.
- Sit your hips back as if reaching for the box. Continue lowering until your butt touches the box.
- Pause completely on the box for one to two seconds. Do not collapse — maintain tension.
- Drive through your full feet to explode back up to standing.
- Squeeze your glutes hard at the top.
- Maintain perfect bar position and brace throughout.
