The calf raise is the primary movement for building the calves — a muscle that responds to a full stretch and lots of quality reps.

Get FormTwin — free on the App StoreStanding calf raises mainly target the gastrocnemius (the larger, visible calf muscle), while seated calf raises — done with a bent knee — bias the soleus underneath. Training both develops the full calf.
Calves respond to a full stretch, a pause, and higher volume than most people give them. Slow the reps down, load the bottom stretch, and train them a few times a week.
Standing (straight-leg) raises hit the gastrocnemius; seated (bent-knee) raises hit the soleus. For complete calves, include both.
