How to do it
Setup
- Stand 4 to 6 inches in front of a sturdy box or bench, facing away from it.
- Shift your weight onto one leg and extend the non-working leg slightly forward off the floor.
- Extend your arms forward at shoulder height to assist with counterbalance and brace your core.
Movement
- Hinge slightly at the hip and bend your working knee to begin a slow, controlled descent.
- Lower yourself under control until your hips gently contact the box without fully collapsing your posture or relaxing tension.
- Pause for a brief moment on the box while keeping the free leg suspended off the floor.
- Drive through the midfoot and heel of the working leg to extend the hip and knee, returning to a fully upright standing position.
Breathing
Inhale as you lower onto the box; exhale forcefully as you drive through your foot to stand.
Cues
- Sit back softly
- Knee tracks in line with your toes
- Reach forward to balance
- Drive the floor away
Common faults
- Crashing down heavily onto the box instead of controlling the descent.
- Slow the eccentric phase and use a higher box until you can touch down softly under muscular control.
- Knee caving inward (valgus collapse) during the ascent or descent.
- Actively engage the gluteus medius to keep the knee tracking directly over the middle toes.
- Rocking forward with momentum to initiate the standing phase.
- Maintain a slight forward torso lean and press straight into the floor from a dead stop rather than rocking off the box.
Safety
- Ensure the box or chair is firmly anchored and will not slip or tip backward.
