What you'll gain
The bent knee shifts work onto the soleus, which straight-leg calf work under-trains.
One dumbbell per leg replaces a dedicated seated calf machine.
The seated position removes balance, so the ankle can move through full range.
Step-by-Step Instructions
- 1
Sit on a bench or box with your feet flat and your knees bent to about 90 degrees.
- 2
Rest a dumbbell vertically on each thigh, close to the knee.
- 3
Hold the dumbbells steady with your hands and sit tall.
- 4
Place the balls of your feet on a low block if you have one.
- 5
Let your heels drop until the calves are fully stretched.
- 6
Push through the balls of your feet, squeeze at the top and lower slowly.
Common Mistakes
Cutting the bottom short, which skips the stretched range the calves respond to.
Bouncing each rep, which lets the tendon do the work instead of the muscle.
Resting the dumbbells on the knee joint, which is uncomfortable and shifts the load.
Rolling onto the toes at the top, which strains the forefoot without adding range.
About This Exercise
The seated calf raise works plantar flexion with the knee bent to roughly a right angle. In this version the load is a dumbbell resting across the thigh just behind the knee, with the forefoot on the floor or a low block. Heels drop into a full stretch, then push up as high as the ankle allows. The bent knee shortens the gastrocnemius so the soleus takes the larger share; with the knee straight the gastrocnemius sits at long length and does more. Training data shows far greater gastrocnemius growth from knee-extended calf work, while soleus growth is similar either way. For a catalog the seated variant is the partner to a standing calf raise, and dumbbell loading keeps it available to home users with no calf station. It fits dumbbell filters and calf specialization blocks.
