How to do the hack calf raise

  1. Step 1: Adjust the sled machine to a comfortable weight.
  2. Step 2: Stand on the sled machine with your toes on the platform and your heels hanging off.
  3. Step 3: Hold onto the handles for stability.
  4. Step 4: Raise your heels as high as possible by pushing through the balls of your feet.
  5. Step 5: Pause for a moment at the top, then slowly lower your heels back down to the starting position.
  6. Step 6: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the hack calf raise by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
