It seems like you don't understand that gaining muscle IS HARD.
Everyone's bodies are different, yes. Your metabolism may be fast. That doesn't make your battle any harder than mine, make sense?
People say that as an excuse for why they haven't reached their goals. And I actually was in no way flaming OP. I was flaming the term "hard gainer".
And guess what, we all have to eat a lot to gain muscle, that's basic stuff. I also weighed 120 at 6 foot with a crazy fast metabolism and you never heard me make excuses for why I wasn't where I wanted to be. I worked my ****ing ass off, ate the amount needed, and did what needed to be done.
Besides the genetic exceptions, we are all hard gainers.
