I am a skinny guy (5’ 11”, 65kg) I’m fast and have a good vertical jump and I have been going to the gym and getting considerably stronger but I haven’t put on any weight yet. I’m conserving using creatine or protein shakes, to help to add some weight, I don’t want to be a body builder or anything just add a bit of weight. I’m going to start a new training program in a week involving weights, running, swimming and plyometrics. Does anyone have any tips?
