Seated Calf Raise Machine: how to do it right
In short: An ankle extension with the knee bent that targets the soleus, loaded at mid-range.
How to do it, step by step
- 1Seated, pad snug on the lower thighs near the knees, balls of the feet on the platform, heels free.
- 2Release the safety and let your heels drop to stretch the calf, without jerking.
- 3Push through the ball of the foot to raise your heels as high as possible.
- 4Control the phase where the calf lengthens, never release the tension all at once.
- 5Slow, continuous rhythm, about 2 seconds up, 2 to 3 seconds down, with no dead time.
The mistake to avoid
Don't do half reps. Drop your heels all the way down.
Other common mistakes
- Bouncing at the bottom with the tendons rather than the muscle: slow the lengthening phase and mark a slight control before pushing back up.
- Truncated range by only going up halfway: raise your heels to the max and lower until you feel the stretch.
- Going too heavy and pushing with your back or hands: reduce the load so that only the calf works.
- Pad placed too high on the thighs: put it close to the knees for a real lever arm.
Muscles worked
- Main:
- Calves
The soleus is the main mover: with the knee bent at 90 degrees, the gastrocnemius is relaxed because it crosses the knee, which shifts all the work onto the soleus. A small contribution from the deep leg muscles (tibialis posterior, toe flexors) to stabilize the foot.
What to replace it with
Same muscle, same part of the movement: these exercises do the same job.
Frequently asked questions
How do I do this exercise?
Seated, pad snug on the lower thighs near the knees, balls of the feet on the platform, heels free. Release the safety and let your heels drop to stretch the calf without jerking, then push through the ball of the foot to raise your heels as high as possible. Slow, continuous rhythm, trunk braced, no dead time.
How far down should I go?
Lower until you feel the soleus stretch at the bottom, then raise your heels to the max. The tension is maximal at mid-range, when the ankle is flat: that is where it is hard. Do not stop at the top where it is easy and do not bounce at the bottom, go for the full range you can control.
I don't feel anything, is that normal?
You should feel a burn in the lower calf, on the soleus. Slow the descent, raise your heels to the max and mark a firm one-second contraction at the top. The soleus is full of endurance fibers: it responds to long sets, 12 to 20 reps, with quality rather than heavy weight.
How fast should I do the movement?
About 2 seconds on the way up, 2 to 3 seconds to let the heels drop. Brake the phase where the calf lengthens well, never release the tension all at once. It is that control that does the work, not speed.
How should I breathe?
Breathe in while the heels drop and the calf lengthens, breathe out as you push the heels up. Keep your trunk braced and your back straight so you do not compensate with your torso.
