Step-by-step technique

Stand facing away from a box, platform, or adjustable bench positioned just behind your legs.

Extend your arms straight out in front of your body for counterbalance.

Balance on one leg, lifting the other leg extended forward off the ground.

Slowly squat down by bending your standing knee — keep your back straight.

Lower under control until your glutes lightly touch the box surface.

Pause briefly, then drive through your heel to stand back up.

Keep your elevated leg extended forward throughout — do not let it touch the floor.

Complete all reps on one side before switching.
