Single-Leg Squat on the Hack Squat Machine
Facing into a hack squat machine, shoulders under the pads, the squat is done on one leg while the other trails behind.
How to do it
Setup
Facing the pads, shoulders under them, one foot on the platform, the other leg free behind.
Steps
- Release the safeties, then sit down on one leg.
- The knee follows the line of the toes.
- Stand up; lock the safeties before switching.
Common mistakes
Pushing off the free foot: it only trails; the working leg lifts. Knee caving on the way up: keep it over the toes. Switching legs with the safeties open: lock them first.
Breathing
Inhale down, exhale up.
