I've been lifting for over the past year steadily about 2-3/wk. Focusing on legs and calfs. I've heard you should rest a day between work outs but a friend, who is a big guy and can bench like 500lbs, told me I don't need to rest a day. Any advice? Also, whenever I eat a lot I get bigger but I lose the cut in my stomach and plus the weight/muscle adds up in my chest and upper body, while I'd like to get bigger and stronger thighs and calfs. Whats your advice? I might be focusing on bench and curls too much.
