Seated Calf Raise Machine
The seated calf raise machine trains the calves with your knees bent at about 90 degrees and a pad pressing down on your thighs. Bending the knee takes the gastrocnemius out of the lift, so the soleus, the deeper calf muscle, does most of the work, making it the best machine for the thicker, lower calf.
Also known as: Seated calf raise, Seated calf machine, Soleus raise machine

What muscles does the seated calf raise machine work?
Primary movers
- Soleus
Assisting muscles
- Gastrocnemius
- Tibialis posterior
- Peroneals
The calf has two main muscles. The gastrocnemius crosses the knee, so it is slack when the knee is bent. The soleus lies underneath and does not cross the knee, so it stays fully active.
Bending the knee to 90 degrees in a seated raise therefore takes the gastrocnemius out and loads the soleus. That is why standing and seated raises are both worth doing.
The soleus is made up mostly of slow-twitch fibres, which respond well to higher reps and long pauses at the stretch.
The seated machine is stable, so you can use a big range and train hard without needing balance.

Common seated calf raise machine mistakes
Bouncing
Rebounding from the bottom uses the Achilles tendon instead of the muscle.
The fix: Pause for a second in the stretch before every rep.
Short range
Half reps skip the stretch and squeeze.
The fix: Go fully down and fully up.
Too heavy
Heavy loads cut the range and encourage bouncing.
The fix: Choose a weight you can control for 10 to 20 reps.
Rushing
Fast reps reduce time under tension.
The fix: Take two seconds up and two seconds down.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Hypertrophy | 3–4 | 10–20 | Moderate to heavy, 1–2 RIR | 60 s |
| Endurance | 3 | 20–30 | Light | 45 s |
| Beginner | 2–3 | 12–15 | Light | 60 s |
Train calves two to four times a week with a mix of standing and seated work. Pause in the stretch on every rep. Add weight in small steps when you reach the top of your range.

Frequently asked questions
What does the seated calf raise work?
The soleus mainly, with the gastrocnemius playing a smaller role.
Seated or standing calf raises?
Seated targets the soleus and standing targets the gastrocnemius. A good calf programme uses both.
How many reps should I do?
10 to 20 reps for most sets, with a pause in the stretch.
Why are my calves not growing?
Most people use short ranges and too little tension. Use a full stretch, a pause and consistent progression.
How often should I train calves?
Two to four times a week, as they recover quickly.
