Leg Press Calf Raise
The leg press calf raise is a calf raise performed on a leg-press machine, pushing the platform with the balls of your feet while your knees stay almost straight. The straight knee keeps the gastrocnemius, the larger calf muscle, at a long working length, and the machine lets you load it heavily through a deep stretch.
Also called: Calf Press on Leg Press, Leg Press Calf Press, Sled Calf Raise · Equipment: machine · Pattern: push
Step by step
- Sit in the leg press with your back flat on the pad. Press the platform up until your knees are straight but not locked, then release the safety catches.
- Slide your feet down so only the balls of your feet sit on the bottom edge of the platform, about hip-width apart, with toes pointing straight ahead and heels hanging off.
- Keep a small, fixed bend in your knees for the whole set so all the movement comes from your ankles.
- Let the platform come towards you under control by bending your ankles until your calves are fully stretched. Pause briefly in the stretch.
- Press the platform away by pointing your feet, rising onto the balls of your feet until your calves are fully contracted.
- Repeat at a controlled pace, with no bounce out of the bottom.
- After the last rep, move your feet back onto the middle of the platform with your knees still straight, re-engage the safety catches and let the sled rest on them.
- Push through the balls of your feet
- Knees fixed, all the movement at the ankle
- Heels back slowly to a full stretch
- Pause at the bottom, no bounce
- All the way up onto the balls of your feet
- Toes straight, even pressure across the foot

What goes wrong, and the fix
Knees bending to help
Fix: Set a small fixed knee bend and keep it; move only at the ankle.
Bouncing out of the stretch
Fix: Bring the platform back under control and pause briefly in the stretch.
Short, choppy reps
Fix: Let the heels travel to a full stretch every rep; use a lighter load if range is short.
Feet too high on the platform
Fix: Place only the balls of your feet on the bottom edge, with heels free.
Feet slipping under load
Fix: Set the balls of your feet firmly on the edge and wear shoes with good grip.
What the research says
Muscle growth · first choiceStrengthRehab & prehabGeneral fitnessEndurance
- Knee angle — In a 12-week trial, straight-knee calf raises grew the gastrocnemius far more than seated calf raises (about 9–12% against under 2%), while the soleus grew similarly with both.
- Stretched range — In an 8-week trial on this exact machine set-up, training only the stretched half of the range grew the inner gastrocnemius by about 15%, against about 7% for full range and 3% for the shortened half.
- Load and effort — Studies show muscle growth is similar across a wide range of loads when sets are taken close to failure, and sets that finish a rep or two short of failure capture most of that benefit.
- Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns, and training a muscle about twice a week is a common way to spread that volume.
- Sets and reps — A common approach is 3–4 sets of 8–20 reps with a brief pause in the stretch, often at the end of a leg session. Many lifters pair it with a seated calf raise to cover the soleus.
