Hello, I have been interested in gaining muscle in my arms. I'm 15 years old, 5'4" and weigh 100 lbs. I eat a lot of junk food and never gain any weight. I am basically a stick, and I wanna change that. I'm interested in buying whey protein, and do push ups and other workouts like that because I can't afford a gym. What work outs can I do and what diet should I follow and is whey protein good for me? If so how do I use it? Another thing, will pull ups work?
