Technique

How to perform Hack Squat

  1. Set up with your back against the pad and shoulders beneath the supports.
  2. Plant both feet on the platform about shoulder-width apart, with a slight outward toe angle.
  3. Extend your legs to take the sled weight and release the machine's catches according to its controls.
  4. Bend your hips and knees to lower the sled while keeping your back supported and feet planted.
  5. Use a depth that preserves that support and control; your thighs do not have to reach a fixed angle to the room's floor.
  6. Extend your hips and knees to raise the sled without snapping the knees backward.
  7. Re-engage the catches before leaving the machine.
