The box squat has you sit back onto a box at your target depth before driving up, teaching proper hip mechanics and eliminating guesswork about hitting depth. This Westside Barbell staple builds explosive hip power by forcing you to generate force from a near-dead stop. The box also allows you to sit back further than a free squat, shifting emphasis toward your posterior chain.
When to use it
Use for explosive strength or learning squat depth.
Who it's for
Powerlifters and intermediate to advanced lifters.
Coaching Note
Touch the box and pause, but do not relax—losing tension on the box makes the lift harder and more dangerous. Your shins should be vertical or angled back at the bottom. If they are forward, you are not sitting back enough.

What are the best tips for the Box Squat?
The box teaches proper squat depth.
Sit back more than you would in regular squats.
Keep tension even when sitting on box.
Great for building explosive strength.
When to Use the Box Squat
Program box squats when teaching proper squat depth, building explosive hip drive for athletics, or during Westside-style training blocks. Use them as your primary squat when recovering from knee issues since the vertical shin position reduces knee stress. Pair with speed deadlifts to develop posterior chain explosiveness.
Common Box Squat mistakes
Relaxing completely on the box.
Squatting patterns like the Box Squat load your entire lower body. This mistake shifts that load to structures that weren't designed to handle it. Stay controlled and let your Quadriceps absorb the work.
Bouncing off the box.
Bouncing or using momentum during the Box Squat takes work away from your Quadriceps and puts your connective tissue at risk. Control the weight through the full range — if you can't, lower the load.
Not sitting back far enough.
A compromised back position during the Box Squat puts your spine under unnecessary shear force. Brace your core and maintain a neutral spine throughout the movement.
Rocking forward to stand.
Squatting patterns like the Box Squat load your entire lower body. This mistake shifts that load to structures that weren't designed to handle it. Stay controlled and let your Quadriceps absorb the work.
Box Squat — who it's best for
Powerlifters and intermediate to advanced lifters.
How to Program the Box Squat
Strength3-5 reps
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
Muscle Growth6-8 reps
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Endurance8-12 reps
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 4-5 sets of 3-5 reps. Rest 2-3min.
