Just wanted to know if taking protein shakes could cause me to gain more body fat, i know it should be takin b4 and after each workout, but i dont know how much of a workout i should do (that makes sense to me). ANY INFO WOULD BE GREAT APPRECIATED. P.S. im doing this for BJJ im hoping to put on some muscle. Im 6" and 170 (skinny). Hopefully you guys could give me some good ab/leg workouts (i was told those are very crucial in bjj). THANKS. If its possible i would like to know how much i should take and what i should take it with. Im a total newb, sorry.
