Box squat

Also called barbell box squat, box squats.

What is a box squat?

A box squat uses a stable box at the bottom of a barbell squat. In the paused version, you sit briefly while keeping your feet planted and your torso braced before standing again. It trains the quadriceps and glutes.

How do you perform a box squat?

Set up

  1. Set a firm, load-rated box inside the rack and adjust the safety bars just below your intended bottom position. Test the box height and position without a bar first.
  2. Place the bar across your upper back, grip it securely and stand to clear the hooks. Take short steps into position with the box behind you and your feet around shoulder width.

Execution

  1. Take a breath, brace your torso and bend your knees and hips together to lower toward the box. Keep your whole foot in contact with the floor.
  2. Settle onto the box gently and pause. Keep holding your brace; do not slump or rock backward.
  3. Push through both feet and stand, keeping the bar balanced over your feet. Reset your breath before the next repetition.
  4. After the final repetition, walk the bar into both rack uprights and lower it onto the hooks.

Common mistakes

  • Dropping the last few inches

    Use a higher box or less weight if you cannot control the contact. Do not fall onto the seat.

  • Rocking to start the ascent

    Hold your position on the box, then stand without swinging your torso forward.

  • Placing the box too far behind you

    Test the position before unracking so you can sit without shifting onto your heels.

Where it fits in a session

If box squats are your main squat, do them before tiring leg accessories.

Keep the same box height and pause when comparing sessions. Increase the load only when every contact and ascent remains controlled.

Variations

  • Two-frame anatomical illustration of a barbell back squat on a white background. On the left a muscular male figure stands upright, seen square from the front, with a loaded barbell across his upper back and both hands gripping it wide; from the front the bar's height on the back cannot be read. The fronts of both thighs are shaded red, as is a strip down the front of each shin. On the right the same figure is at the bottom of the rep, seen from the side and a little behind, hips at or below the knees in a deep squat with the feet flat and the toes turned out slightly; from this angle the red shading covers the fronts of the thighs and the inner thigh running up toward the groin. The buttock is in view in that frame and is not shaded, and nothing on the back of the thigh is shaded in either.
    Back squatChanges direction without sitting on a box.
  • Touch-and-go box squat — Touches the box as a depth marker without taking a seated pause.
  • Bodyweight squat to a boxUses the box without a barbell; choose a height that lets you stand smoothly.

Frequently asked questions

How high should the box be?

Choose a height you can reach with both feet planted and a controlled descent. Test it without the bar, and use the same height for the whole set.

Should you sit down or just touch the box?

Both versions are used. For a paused box squat, take a brief seated pause while staying braced. A light touch uses the box only to mark depth; decide which version you are doing before the set.

Is this the same as a bodyweight squat to a chair?

Both use a seat, but a barbell box squat also requires a secure rack setup, safety bars and control of the bar during the pause. Start without a bar if the seat position is unfamiliar.
