What music do you train to?
I listen to a plethora of music, almost everything (except country). I've gone through trying everything while training, hitting bags, shadowboxing, techniques, or even forms, but I find the BEST that I enjoy the most seem to be .... Drum 'n Bass.
I think it has to do with the beats, the groove, the intensity as well... everything into one. It's not TOO HARD, like some heavy ass metal, it's not too light, like softer electronic music, and it's not too "groovy" either like house music or even some hip-hop.
But I would say I understand why people enjoy training to hip-hop also, it's got a similar "edge" to it. You wanna move your body... and you enjoy doing it. Almost like dancing, you know?
