i train them twice a week... training 1 heavy weight training 2 light weight and more reps.
training 1 (at leg day):
seated calf raises 3 sets 8-10 reps
donkey calf raises 3 sets 8-10 reps
standing calf raises 1 set 8-10 reps
training 2:
standing calf raises 2 sets 20- 25 reps
seated calf raises 2 sets 15-20 reps
i dont think its nessesary to train them if youre not doing contests as bb'er altough some peopel say that a well developed anterior tibialis adds more depth and
symmetry. It will make your calves appear larger from the front and side.
remember to train youre calves in the "pain zone" when they hurt they grow, when they dont they dont
