Calf Raises on Leg Press Machine: How To, Muscles Worked & Common Mistakes

Calf raises on leg press machine are one of the most underutilized calf exercises in the gym. The leg press machine allows you to load your calves with significantly more weight than standing or seated barbell variations — and the reclined position removes the balance and stability demands entirely, letting you focus purely on the calf contraction. It’s also one of the most convenient calf exercises you can do, since you’re already on the machine after your leg press sets.

How the Calf Raises on Leg Press Machine Differs from the Other Calf Raise Variations

You have three calf raise pages on your site and each one has a distinct profile:

• Standing barbell calf raise — knees straight, maximum gastrocnemius activation, full stretch with a platform. See our Standing Barbell Calf Raise page
• Barbell seated calf raise — knees bent at 90 degrees, maximum soleus isolation, good loading with a barbell. See our Barbell Seated Calf Raise page
• Leg press machine calf raise (this page) — legs extended at roughly 30–45 degrees, knees slightly bent, hits both gastrocnemius and soleus, allows the heaviest loading of the three, convenient after leg press sets

The slightly bent knee position on the leg press machine means both the gastrocnemius and soleus are meaningfully involved — making this a good all-round calf exercise when you want to hit both muscles in one movement.

Calf Raises on Leg Press Machine – Muscles Worked

Primary muscles:

• Gastrocnemius — heavily involved due to the relatively extended knee position
• Soleus — also significantly involved due to the slight knee bend compared to fully standing

Secondary muscles:

• Tibialis posterior — assists with ankle stability throughout
• Peroneals — assist with lateral ankle stability throughout

How to Perform Calf Raises on Leg Press Machine

1. Sit in the leg press machine as you normally would for a leg press. Select your weight.
2. Extend your legs until they are almost fully straight — keep a very slight bend in the knees throughout to avoid locking out the joint.
3. Move your feet to the very bottom edge of the platform — only the balls of your feet and toes should be on the platform, with your heels hanging freely off the bottom edge.
4. Release the safety handles and hold the platform steady with your legs extended.
5. Let your ankles drop into a fully dorsiflexed position — heels dropping toward you — to get the full calf stretch at the bottom.
6. Push through the balls of your feet and extend your ankles as far as possible, driving the platform away from you with your toes.
7. Squeeze your calves hard at the top and hold for 1–2 seconds.
8. Slowly lower back to the fully stretched position over 2–3 seconds.
9. Repeat for your desired reps, then re-engage the safety handles before releasing.

Calf Raises on Leg Press Machine Pro tip: Keep your legs as still as possible throughout — only your ankles should move. If your knees are bending and straightening to help push the platform, you’ve turned it into a leg press. Lock your leg position and isolate the movement purely to ankle flexion and extension.

Calf Raises on Leg Press Machine – Common Mistakes to Avoid

1. Feet too high on the platform If your whole foot or most of your foot is on the platform, your ankles can’t fully extend or flex and you lose most of the range of motion. Move your feet to the very bottom edge so only the balls of your feet are in contact — your heels should hang completely free.

2. Not going through a full range of motion Same principle as all calf raises — partial reps that skip the full stretch at the bottom are far less effective. Let your ankles drop fully at the bottom of every rep and feel the complete stretch before pushing back up.

3. Bouncing at the bottom Using the stretch reflex to bounce the platform back up removes the tension at the most critical point. Pause briefly at the fully stretched position before each rep — this is what your existing page correctly warns against.

4. Knees bending to assist The most common form breakdown on this exercise. When the calves fatigue, the natural compensation is to start bending and extending the knees to help push the platform. Once this starts happening, your set is effectively over — your calves have stopped working. Stop the set and rest rather than continuing with knee-assisted reps.

5. Locking out the knees Fully locked knees under load on the leg press puts the joint in a vulnerable position. Keep that very slight bend throughout every rep — it also keeps a little tension on the quads and hamstrings as stabilizers.

6. Using the safety handles incorrectly Always engage the safety handles before you remove your feet from the platform. On a heavy loaded leg press, releasing the machine without the safeties engaged while transitioning from calf raises back to your seated position is dangerous.

A Practical Advantage: Convenience

One of the best things about this exercise is timing — after finishing your leg press sets, simply shift your feet to the bottom of the platform and go straight into calf raises without changing equipment or moving to a different station. This makes it easy to get your calf work done efficiently at the end of a leg session, especially when the gym is busy and dedicated calf raise stations are occupied.

Where It Fits in Your Workout

Calf raises on leg press machine work best at the end of your leg session — either immediately after your leg press sets as a convenient drop-set style finisher, or as part of a complete calf circuit alongside standing and seated raises. Because the machine allows heavier loading than most calf exercises, some lifters use this as their primary heavy calf movement and follow it with higher-rep standing raises for the stretch and pump.
