Seated Calf Raise
The seated calf raise trains the calves with your knee bent, which shifts more of the work onto the soleus, the deeper calf muscle that sits under the more visible gastrocnemius. Sitting with a pad across your thighs and your toes on a platform lets you drive through a full range of ankle motion under load, something that's harder to control standing up. It's a simple, low-skill exercise that rewards a slow, deliberate tempo more than heavy weight.
Why it works
The calf muscles raise your heel by pointing your ankle, but which calf muscle does most of that work depends on how bent your knee is. With your knee bent at roughly 90 degrees, the gastrocnemius is shortened and mechanically less able to contribute, which shifts a larger share of the work onto the soleus underneath it. Because the soleus is a slow, fatigue-resistant muscle built for holding posture all day, it tends to respond well to higher rep ranges and a deliberate pause at the top and bottom of each rep, rather than the heavier, lower-rep loading that suits many other muscle groups.
Set up
- Sit at the seated calf raise machine with your thighs under the pad and your toes on the platform, heels hanging off the edge.
- Adjust the pad so it rests securely just above your knees before you unrack the weight.
- Let your heels drop below the platform to feel a light stretch through your calves.
- Keep your torso upright and your hands lightly resting on your thighs or the pad for stability.
How to do it
- Press through the balls of your feet to raise your heels as high as you can.
- Pause briefly at the top, squeezing your calves.
- Lower your heels back down under control, past the platform edge into a light stretch.
- Pause briefly at the bottom before starting the next rep.
- Keep the movement smooth and unrushed through the whole range, top to bottom.
- Repeat for the full set without bouncing at the bottom to generate momentum.
Form cues
- Full range, heels dip below the platform.
- Pause and squeeze at the top.
- Slow and controlled, no bouncing.
- Knees stay under the pad the whole set.
Breathing: Exhale as you press up through your heels, inhale as you lower them back down.
Common mistakes
Using a short, partial range of motion instead of dropping the heels fully below the platform.
Fix: Let your heels sink into a full stretch at the bottom of every rep; the bottom range is where the soleus gets most of its training stimulus.
Bouncing out of the bottom position to help start the next rep.
Fix: Pause briefly at the bottom and press up deliberately, rather than letting the stretch rebound you into the next rep.
Rushing through reps without pausing at the top.
Fix: Hold the top position for a moment and squeeze your calves before lowering; that pause is what turns the movement into real work instead of a quick bounce.
Letting the knees slide out from under the pad as the weight gets heavier.
Fix: Reset the pad position and keep your knees tucked underneath it throughout the set; a shifting pad changes the angle and reduces the stretch.
How to program it
- The calves recover quickly and respond well to frequent training, so two or three sessions a week with this exercise is a reasonable target.
- Three or four sets of 12 to 20 reps suits the calves better than lower rep ranges, since they're built for sustained, repetitive work.
- A slow tempo, roughly two seconds up and two seconds down, tends to build more calf size and strength here than rushing through a heavier weight.
- Pair it with a straight-knee calf raise like the standing dumbbell version in the same week to train both the soleus and the gastrocnemius.
Safety notes
- Don't drop the heels into an aggressively deep stretch under heavy load; a moderate stretch is enough to get the benefit without straining the Achilles.
- Keep the pad snug but not painfully tight across your thighs before you start the set.
- Ease into the exercise with a lighter warm-up set first, since the calves and Achilles tendon can feel stiff if you load a deep stretch cold.

Frequently asked questions
How many sets and reps should I do for the seated calf raise?
Three or four sets of 12 to 20 reps a couple of times a week is a solid range, since the calves tend to respond well to higher reps and frequent training.
What can I do at home without a seated calf raise machine?
A dumbbell held across your lap while sitting on a sturdy chair with your toes on a step or block reproduces the same bent-knee calf pattern.
Why does the seated version feel different from standing calf raises?
Bending the knee shortens the gastrocnemius and shifts more of the work onto the soleus underneath it, so the seated version trains a slightly different part of the calf than a standing raise.
How is this different from donkey calf raises?
Donkey calf raises load the calf from a bent-over hip position with a deeper stretch and more total range, making them a more demanding progression once seated raises feel manageable.
Why do my calves barely feel sore after this exercise?
The soleus is a fatigue-resistant muscle built for endurance, so it often needs higher reps and a slower tempo over several sessions before soreness shows up the way it does with other muscle groups.
