Seated Calf Raise Machine
The seated calf raise is a machine exercise in which you sit with a pad across your thighs and raise your heels from a deep stretch to as high as they go. Because the knees stay bent, it trains mainly the soleus, the deep calf muscle, rather than the gastrocnemius that standing calf raises train.
Also called: Seated Calf Raise, Machine Seated Calf Raise, Knee-Bent Calf Raise, Soleus Raise · Equipment: machine · Pattern: push
Step by step
- Adjust the thigh pad so it sits snugly on your thighs just above your knees, with your knees bent to about 90°.
- Sit down and place the balls of your feet on the edge of the foot block with your heels hanging free. Keep your feet about hip-width apart and your toes pointing forward.
- Push up through the balls of your feet to lift the pad slightly, then release the safety lever.
- Let your heels sink slowly until you feel a deep stretch in your calves, and pause there for a moment.
- Push through the balls of your feet, on the big-toe side, to raise your heels as high as they go.
- Hold the top briefly, then bring your heels back down under control to the deep stretch.
- After the last rep, raise your heels, re-engage the safety lever and let the weight settle onto it before you step out.
- Heels down slowly to a deep stretch
- Pause at the bottom, no bounce
- Push through the ball of the foot and big toe
- Heels as high as they go
- Knees stay bent, pad snug on your thighs

What goes wrong, and the fix
Short, bouncy partial reps
Fix: Take every rep from a deep, paused stretch to a full heel rise.
Cutting the stretch short
Fix: Let your heels sink fully under control before each rise.
Rolling onto the little-toe side
Fix: Press through the ball of the foot under the big toe and keep the ankle straight.
Load too heavy to reach the stretch
Fix: Pick a load you can move from a full stretch to a full heel rise every rep.
Feet too far onto the block
Fix: Set just the balls of your feet on the edge of the block, heels free to drop.
Loose thigh pad
Fix: Set the pad snug on your thighs just above the knees before releasing the lever.
What the research says
Rehab & prehab · first choiceEndurance · first choiceStrengthMuscle growthGeneral fitnessSport performance
- Seated and standing — In a 12-week study where each person trained one leg seated and the other standing, both grew the soleus similarly, but the seated leg barely grew the gastrocnemius (about 1–2% against 9–12% standing). Many programmes include both.
- Stretched range — In a leg-press calf-raise study, training the stretched half of the range grew the gastrocnemius more than the full or shortened range. No equivalent study has tested the soleus on a seated machine.
- Load and effort — Research finds muscle growth is similar across a wide range of loads when sets are hard, and true failure adds only a trivial-to-small benefit. Seated calf raises are commonly done for about 8–20 reps.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns.
- Tempo — Studies show growth is similar across rep speeds from about half a second to eight seconds when sets are hard. Many lifters add a pause at the bottom to take out the rebound.
- Endurance — Research finds local muscular endurance tends to favour lighter loads and higher reps, and the soleus is a mainly slow-twitch muscle.
