How to perform the Hack Squat Calf Raise

  1. Set your back against the hack squat pad with the balls of the feet on the lower edge of the platform and the heels hanging off.
  2. Straighten the legs against the shoulder pads so the gastrocnemius carries the load along the angled sled.
  3. The hack squat angle loads the calves through the shoulders on a fixed, stable path.
  4. Lower the heels below the platform edge for a full stretch at the bottom of the rep.
  5. Pause in the deep stretch rather than bouncing the sled off the Achilles to rebound.
  6. Drive up to full plantarflexion on the balls of the feet, squeezing the calves before lowering.

Suggested working range: 12–20 reps. Default progression: double progression.

Common mistakes

  • •Bouncing the sled off the Achilles at the bottom instead of pausing in the stretch.
  • •Bending the knees, which reduces the gastrocnemius emphasis on the angled sled.
  • •Doing short partial reps that never reach a deep stretch or a full squeeze.
  • •Letting the heels stay above the platform edge rather than dropping into a stretch.
