hey everyone. I currently play High school baseball and Im a catcher. The only problem is that I am too small. I am 5 feet 9 inches and I weigh 147 pounds. I am a junior by the way(11th grade). I am not worried about my height. What I am worried about is my weight. I have been working out forabout a year now and I have gained a little bit of muscle but not much. I have taken NO2 pills. I have taken Protein. I have taken muscle milk, and none of them seem to work for me. I have really started taking it serious now for about a week. I workout with my friend who really knows what he is doing, an he told me to get some weight gainer and NO explode, so i did. I really want to get up to at least 170 pounds by the end of the summer. I really need some help, so please tell me what I can do to get up to 170 pounds A.S.A.P.
