Box Squat
The box squat has you sit back and down onto a box set at or near parallel, pause briefly with the weight settled, then drive back up without a bounce. Powerlifters use it to build strength from a dead stop and to teach a squat pattern that loads the hips and hamstrings more than a typical knee-forward squat, while the box itself removes any guesswork about depth.
Why it works
Sitting back to reach the box instead of dropping straight down shifts more of the work onto your hips and hamstrings, since your hips travel further back relative to your knees than in a standard squat. Pausing on the box removes the elastic rebound your tendons normally provide at the bottom of a squat, so when you drive back up, your quadriceps and glutes have to generate force from a genuine dead stop instead of borrowing momentum from the stretch. Your lower back and core hold your torso rigid throughout, and your adductors and abductors work to keep your knees tracking correctly as you sit back and stand up again.
Set up
- Set a box or bench at a height where your hip crease drops to about the same level as your knee when you sit on it.
- Load the bar on a rack at upper-chest height and step under it to rest it across your upper back.
- Unrack the bar and walk back until the box is directly behind you, feet set slightly wider than your normal squat stance.
- Turn your toes out a bit more than usual to help your hips travel back to the box.
- Brace your core and take a breath before you start the descent.
How to do it
- Push your hips back and down toward the box, keeping your shins closer to vertical than in a regular squat.
- Sit fully onto the box, letting your hips relax for a brief moment while your torso and core stay braced.
- Keep your weight balanced over your midfoot, don't let it shift onto your heels or toes as you sit.
- Drive explosively back up off the box, pushing the floor away hard the instant your weight settles.
- Stand all the way to lockout with the bar path staying straight over your midfoot.
- Reset your brace at the top before your next descent.
Form cues
- Sit back to the box, don't drop straight down.
- Pause without collapsing your torso.
- Drive up hard the moment you feel the box.
- Knees track out over your toes the whole rep.
Breathing: Take a breath and brace before you descend, hold it through the pause on the box, then exhale once you've stood back up to lockout.
Common mistakes
Bouncing off the box using the box's rebound instead of a controlled dead-stop drive.
Fix: Let your hips relax fully for a beat, keep your torso braced, and drive up using muscle, not momentum from the bounce.
Letting the torso collapse forward when the hips touch down.
Fix: Keep your core braced and your chest up through the pause so your spine position doesn't change when you sit.
Setting the box too low and losing tension in the bottom position.
Fix: Set the box so your hip crease reaches about knee level, low enough to be a real squat but not so low you lose control.
How to program it
- This is a loaded compound squat pattern, so once a week as your primary lower-body strength session is the right default, whether you use it as your main squat or as a dedicated technique and power day.
- Because the dead-stop start is demanding on your nervous system, keep sets in the two to five rep range rather than chasing higher-rep sets here.
- Many lifters use box squats specifically as a lighter, faster-bar-speed day paired with a heavier free squat elsewhere in the week, since the goals of the two sessions are different.
Safety notes
- Set the box height carefully. Too low can push your hips and lower back into a position you can't control under load.
- Use a spotter or rack safety pins when adding real weight, the pause on the box means there's a moment you're not actively driving the bar.
- If your lower back rounds when you sit onto the box, raise the box height until you can keep a braced torso through the pause.

Frequently asked questions
How low should the box be for a box squat?
Set it so your hip crease reaches roughly the same level as your knee when you sit down, which usually matches parallel or just below for most lifters.
Do I pause on the box or just touch it?
A true box squat has you sit fully and briefly relax your hips before driving back up. A light touch-and-go is a different drill, closer to a squat to a bench.
Box squat vs regular squat, what's the real difference?
The box squat sits your hips further back and pauses at a dead stop, building hip and hamstring strength and explosive power off the bottom. A regular squat keeps more continuous tension and a more upright shin angle.
Why does my lower back round when I sit on the box?
That usually means the box is set too low for your current hip mobility and control. Raise it a bit until you can keep your torso braced through the full sit.
