For my calves, will doing seated calf raises make them grow? Or do I need to target mainly the Gastrocnemius? Their isnt a donkey calf raise machine or a standing calf raise machine at my gym, just a seated one, so I could either so standing calf raises in the squat rack, do one legged calf raises on a step, do two legged calf raises on a step with a DB in one hand or do what Im doing now - seated calf raises to 12-15 reps at the gym, very high rep two legged calf raises on a step once a week at home...
