Ugh... This "get bigger" trend is freaking annoying. The reson why I don't suggest it for MMA is because there are weight classes. In that case, being big (carrying excess weight) does not help! I'm not going to suggest anything really to anyone who is going to post first, "How to I get bigger?" only to turn around 9 months to a year or so down the line to see the same person posting "I've got a fight, I need to drop 20lbs quick!"
Besides, we don't even know how old the OP is. He might just be in his teens, in which case he will probably gain significant amounts of weight once he stops growing into his full height. It happens to everyone.
It doesn't matter if you agree or disagree
... As long as I don't bore you and I spark a moment of thought, my goal is achieved
