Box Single-Leg Assisted Pull-Up
The pull-up with only one foot on a box below the bar, the other leg hanging; one leg helps, so the arms take more than with both feet down.
How to do it
Setup
Hang from the bar, overhand grip, one foot on a box under you with that knee bent, the other leg hanging free.
Steps
- Pull with the arms, pressing lightly through the foot on the box.
- Rise until the chin clears the bar.
- Lower slowly; switch the supporting leg on the next set.
Common mistakes
Stepping up on the box leg: it assists, it does not stand you up. Hips twisting toward the box: keep them square under the bar. Always the same leg on the box: alternate between sets.
Breathing
Exhale on the pull, inhale lowering.
