Muscles worked
The seated calf raise puts most of the work on the soleus, the broad muscle beneath the gastrocnemius. With your knees bent, the gastrocnemius is shortened, and because it attaches above the knee it cannot contribute much force in that position. That is why the seated version complements the standing ones, where the gastrocnemius takes a bigger share. The soleus is often described as an endurance muscle that works a great deal whenever you stand and walk.
Common mistakes
- You help with your arms. It is easy to pull on the handles or push the pad down with your hands. Rest your hands lightly and let your calves do the work.
- The pad sits loose on your thighs. If it is set too high or too loose, part of the movement is lost before the weight even lifts. Adjust it snugly against your thighs, just above the knees.
- You let go of the weight after the last rep. Without the safety catch, the weight drops while your calves are tired. Rise onto your toes one last time and swing the catch back before you relax.
Variations and alternatives
- The standing calf raise with straight knees works the gastrocnemius more, and together the two exercises cover the whole calf.
- The leg press calf raise also keeps your legs straight, for when there is no standing calf machine.
Without a machine, you can sit on a chair with a heavy rucksack on your knees and the balls of your feet on a weight plate or a thick book.
Sets and reps
The soleus often tolerates plenty of reps, so 12 to 20 per set, over three or four sets, is a common setup. Heavy, low-rep sets rarely add anything here. There is more on the ranges in the guide to sets and reps.
Only add weight once every set gets to the top of the range without the depth at the bottom shrinking, following the principle of progressive overload. If the machine is plate-loaded, you can go up one small plate at a time. Pair it with a standing calf exercise in the same session, so both muscles get their share.
