I used to be completely unable to gain weight. I would eat and eat and work out and nothing.

Since boot camp (Dec 7th 09 - March 7th 2010), I went from 128 lbs to 145 lbs. Since THEN, I've gained another 10 lbs of muscle via working out and eating healthy.

Honestly, a lot of gaining weight is in your diet. Try to hit the gym once a day or maybe once every other day, and make sure you eat a LOT of protein directly after working out.

I eat around 10,000 calories a day. I eat my weight in grams of protein, and double my weight in grams of carbs. So I eat around 150g protein / day, and 300g carbs.
