It′s funny but if I do calf raises or basically any repetitive movements solely for calves they seem to respond by atrophying.
But they have grown from just squatting and deadlifting, not lots mind you but they are significantly improved.
Just for kicks I thought I′d try standing calf raise but statically for two minutes, first holding a trap bar with 145 lbs., the problem though was my back muscles cramped up the next day. I suppose after deadlifting to failure, followed by a serious set of dips, holding that bar was just too much.
Fwd to the next workout and at the end of squats, and chins, I did one legged calf raise static hold for two minutes each leg and bingo it did the trick ( I think).
Funny thing though was the next evening I felt more tired than usual and a bit irritable. Just adding that little bit extra pushed me over my limit, not too far, but far enough nonetheless
