Alright, I'm on the football team and this summer I went to probably half of the conditioning sessions and then I started to slack off and not go and eventually stopped altogether. I want to build muscle everywhere but at first the upper body, I don't have any equipment and can't go to the gym so I wanted to know if there were any good at home workouts you guys had for building upperbody strength..and I also want to gain weight I weigh 115 but I'd like to be at least 145. Can anybody help please? Thanks I appreciate it.
