Hi there I have just turned 18 and I am a semi pro footballer. I train 3 days a week moderate to high intensity for around 12 hours. I go to the gym 1 day a week for an hour. I am looking to gain weight as I am tall 6 ft 2 and skinny build 11 st 1. I need a programme that I can do at home with no weights that will help me gain size/ muscle mass. I also need food ideas and a plan if possible
Any advise taken on bored thanks
