Dumbbell Seated One-Leg Calf Raise
The dumbbell seated one-leg calf raise trains one calf at a time while you sit, using a dumbbell across your knee for resistance. Working one leg alone removes the stronger leg's ability to cover for the weaker one, so you get an honest measure of each calf's strength and a fuller range of motion than most standing calf work allows.
Why it works
Bending the knee to 90 degrees slackens the gastrocnemius, the calf muscle that crosses the knee, and shifts more of the work onto the soleus underneath it, the muscle that does most of the job when you walk or stand for long stretches. Doing the raise on one leg at a time also means each calf carries the full load instead of splitting it with its partner. Most people have a dominant side from years of favoring one leg in daily movement, and this exercise is one of the few calf drills built to expose and close that gap rather than let it hide.
Set up
- Sit on a bench or chair with your knees bent to about 90 degrees.
- Place a dumbbell upright on top of one knee, holding it steady with both hands.
- Set the ball of that foot on a low platform, a weight plate, or a step, with your heel free to drop.
- Rest your other foot flat on the floor for balance, without using it to help lift.
How to do it
- Let your working heel drop down as far as feels comfortable, feeling a stretch through the calf.
- Press through the ball of your foot to lift your heel as high as you can.
- Pause for a moment at the top and squeeze the calf.
- Lower your heel back down under control, resisting the urge to let it drop.
- Complete every rep on one side before switching the dumbbell and the platform foot to the other leg.
Form cues
- Full stretch at the bottom, full squeeze at the top.
- Keep the movement in the ankle, not the knee.
- Control the descent, don't drop the heel.
- Dumbbell stays vertical and steady on the knee.
Breathing: Exhale as you press up through the ball of your foot, inhale as you lower your heel back down.
Common mistakes
Bouncing at the bottom of the stretch to build momentum for the next rep.
Fix: Pause briefly at the bottom so the next rep starts from a dead stop, not a bounce.
Only lifting through a short range near the top.
Fix: Let the heel travel all the way down first, so you train the full range the seated position allows.
Letting the resting foot push off the floor to assist the lift.
Fix: Keep the resting foot light on the floor for balance only; the working leg should do all the lifting.
Rushing through reps on the stronger leg and slowing down on the weaker one.
Fix: Match the tempo and rep count exactly on both sides so you don't reinforce the imbalance you're trying to fix.
How to program it
- Three sets of 12 to 20 reps per leg suits most people, since calves respond well to higher rep ranges than heavier, lower-rep work.
- This is light isolation work, so training it three or four times a week is reasonable if your ankles feel fine the next day.
- If one leg is noticeably weaker, start your working sets on that side while you're freshest.
- A one- or two-second pause at the top of each rep adds difficulty without needing a heavier dumbbell.
Safety notes
- Hold onto the bench or a nearby support if balance feels shaky, especially early on.
- Skip a deep bottom stretch if your ankle or Achilles feels irritated that day, and use a smaller range instead.

Frequently asked questions
How many sets and reps for the seated one-leg calf raise?
Three sets of 12 to 20 reps per leg is a solid range, since calves tend to respond better to higher reps than heavy, low-rep sets.
Why is one calf weaker than the other?
Most people favor one leg during walking, running, or standing, so training seated raises one leg at a time helps close that gap instead of letting the stronger calf compensate.
Can I do this without a dumbbell?
Yes. Bodyweight alone on one leg is still a real challenge for most people; add the dumbbell once bodyweight reps stop feeling hard.
Seated or standing calf raise, which is better?
They train different parts of the calf. Seated raises bend the knee and emphasize the soleus, while standing raises with a straight knee put more demand on the gastrocnemius, so doing both covers the muscle more completely.
