Ok so im 14. I started lifting last year and got on some whey protein for the summer. I was 103 last summer and now i'm 138. Im 5'10". I bench 160x1. Squat 275x5. Curl 30x5 both arms. I want to know what i need to work on and how. Also ive been trying to get bigger but just cant. Im in wrestling season now and have to maintain a 125 weight class so i cant put on lots of fat. Im also DEFINITELY NOT looking to take any supplements
other than some whey and multivitamins.
