I do heave standing calf raises with bar on back full range and when I can't do any more I do partials. After 3 or 4 sets ( I don't rest long Inbetween just keep hammering em) I move to seated ones and hit up full range until I can't then ill grab that handle and use my whole body to help move not for as many more reps as I can. These alone make em grow for me. I always go heavy as I can for calfs... You walk on em all day they are used to strenuous light weight, to build big calves you need heavy weight to stimulate them more than they are used to.! I also do them 3 days a week lately!
