Hi, i really want to gain muscle on pecs,bicep/tricep,back and stomach. At the moment im 17 years old and male, im 5 ' 8 and weigh about 10 stone 4. I was wondering how i could do this without going to the gym, because i dont have enough time or money to go! Any help i will be grateful for, thanks!
