Being naturally too skinny, how do I gain weight? 115lb guy?
I eat a lot, but I never gain weight, and if I did, I gain it 3-8 pounds and lose it almost in a week if I stop trying to gain weight. I don't exercise often, how should I begin? what should I do? Can I start at home since I'm soo thin and too embarrased to go to a gym? I'm a guy, and I'm only ~115 lbs (my natural weight I keep coming back to), 21 year old. I'm also 5'10"
