While amazing martial artists and amazing athletes, many Brazilian fighters seem to tank fast when getting wrestled/grappled for any significant amount of time. Is BJJ cardio dfferent from Wrestling based cardio? I have trained some BJJ and I was gassed after rolling for an hour, what is the difference from training wrestling for an hour? Anderson gassed vs. Chael Vitor gasses against everyone Aldo gassed vs. Hominick Cigano tonight Silva vs. Fitch The list goes on and on. Too much sun, not enough treadmill?
