Setup
Position your body in the hack squat machine with your back against the back pad and your shoulders under the shoulder pads.
How to perform
- Place your feet on the platform, roughly shoulder-width apart, with your toes pointing slightly outwards.
- Inhale and lower the weight by bending your knees until your thighs are parallel to the platform, or slightly deeper.
- Exhale and press through your entire foot to push the platform back to the starting position.
- Extend your legs, but avoid locking your knees at the top.
Form cues
- Maintain contact between your back and the pad throughout the movement.
- Keep your heels on the platform.
- Your knees should track in the same direction as your feet.
Common mistakes
- Lifting your heels off the platform.
- Allowing your knees to collapse inwards.
- Not performing the exercise through a full range of motion.
- Rounding your lower back off the pad.
