What gets you revved up? I notice some people like hardhouse ortrance, tbh it makes my heart go 200 mph and I cant concentrate. I like something with an edge to it, that makes you angry, but not something that makes you think. For me MMA training = Metal, its all cerebral and its good for technique to just go through the motions without having to think about it, but at the gym its all hiphop. You can feel the rhythm and just get down to business.
