Not sure if this is the right section for this thread but I guess its considered training.
So I've been doing mma for a while now and I've noticed one of my friends when he fights its like he's a whole different person. He's the nicest person I know but when he puts the gloves on and the fight starts he's so aggresive and its like he blocks everything out and hits don't phase him. Its actually kinda scary to spar with him because its like he gets stronger when he gets hit. I asked him about it and he doesn't even realize it happens, I was wondering if there is a way to attain this mindset through training or if it just comes with experience or if you have it or you don't?
