My calves havent ever really grown much. Well i read a post by Jbigdog69 reccomending holding a contraction at the top. Well i tried it out but put my own spin on it, doing it unilaterally for 2 sets a side before doing both legs together. As a result i cant train calves twice a week anymore, they just arent recovering fast enough. Im going to have to switch to training them every 5th day eg, monday, saturday, thursay, tuesday. If you dont hold a contraction at the top of your calve workout i suggest you try it it bloody hurts!
