my inner calf muscle is larger than the outer you must do sets in three positions..
toes pointed inward
toes pointed outward
toes pointed frontward but genetics will always determine growth
Toes Inward: Outer calf
Toes Outward: Inner calf
Toes Forward: Overall
Also, what I am going to do for calves from next week is train them every day I am training (6 days.) Probably between Seated calf raises, standing calf raises and one other. I tried leg press calf raises, but didn't get a great flex, so might see what else there is and do that. I believe in giving everything a ago. Good luck!
