For me there is no reason why to go up in weight class, because when you go up in weight class you have to fight bigger guys - then you have to train against bigger guys. The guys are not better, they're heavier, but it means you have more chance to get hurt.
Georges St-PierreYou donโt get better on the days when you feel like going. You get better on the days when you donโt want to go, but you go anyway. If you can overcome the negative energy coming from your tired body or unmotivated mind, you will grow and become better. It wonโt be the best workout you have, you wonโt accomplish as much as what you usually do when you actually feel good, but that doesnโt matter. Growth is a long term game, and the crappy days are more important.
