Hey everyone my name is Jeremy and im a 15 year old highschool baseball player. I'm currently "6'1" and weigh 140lbs...thin. I believe I'm a hardgainer because I eat a good amount of food(roughly 1000 calories every morning)... mainly clean and hardly gain weight.
I've been working out for around 12 weeks now 3 days a week. I've currently only gained around 1-2 lbs. of muscle if any. I'm just wondering if anyone can show me a good routine for building muscle mass.
All help appreciated
