How to do the Box Squat
Set up. Set a box or bench behind you at a height where your thighs are about level with the floor when seated. Set up as for a back squat in a rack with the bar on your upper back.
- Sit your hips back and down to the box under control.
- Pause briefly on the box while staying tight.
- Drive up to standing.
Form cues
- Touch the box, do not collapse onto it.
- Keep your shins fairly vertical.
- Stay braced throughout.
Common mistakes
- Dropping onto the box.
- Rocking back to get off it.
Take care. Use a stable box and set the rack's safety pins below the box height.
Muscles worked
Main target: Quads. The quadriceps are four muscles at the front of the thigh. They straighten the knee: squats, lunges, leg presses and every stair.
On the way: Glutes and Hamstrings.
Its other side: Hamstrings and Glutes, in the knees and hips pattern.
What to pair it with
Movements that round out a workout with the Box Squat, from the same catalog the StatBlockFit app logs.
- Romanian Deadlift Superset partner: it trains the other side of the knees and hips pattern, so the two can alternate.
- Seated Calf Raise Same legs session: it trains the calves.
- Cossack Squat Same legs session: it trains the adductors.
- Hip Abduction Often left out: it trains the abductors, a job the moves above leave undone.

Alternatives and swaps
The same main muscle with other equipment: a swap never changes the muscle a workout trains.

Gym or cable swap

A swap describes the movement, not your body: if a joint hurts, ask a professional before you train it.
Working weight and 1RM calculator
Enter a set you did: the weight, the reps and how many more reps you had left in you. The estimate is the formula the StatBlockFit app uses for its records, weight × (1 + (reps + reps in reserve) ÷ 30); above 12 reps it is rough.
Training zones
| Zone | Share of 1RM | Usual reps |
|---|---|---|
| Strength | 85 to 90 % | 3 to 6 |
| Muscle growth | 70 to 80 % | 6 to 12 |
| Endurance | 60 to 65 % | 15 to 20 |
A warm-up before the working sets: 50 % for 5, 70 % for 3 and 85 % for 1, each rounded down to a plate.
Common starting points, not a prescription: the right weight is the one you can lift with good form for the reps you planned.
Variations and preparation
A variation of: Back Squat.
Other variations of the Back Squat: Front Squat, Hack Squat, Smith Machine Squat, Pause Squat, Belt Squat, Goblet Squat and Leg Press.

Track it in StatBlockFit
In the StatBlockFit app the Box Squat is logged set by set: the app suggests your next weight after each session, times your rests, keeps your records and shows the 72-hour recovery of every muscle on its training map. The training guide explains how.
