Dosent everyone whos cardio been doubted say prior to every fight that they are in the best shape of their life and that they train cardio harder then ever... sound like the same old song once again.
But i actually think that BJ:s cardio is way better then it used to but is nowhere near the cardio of Sherk. Sherk will put on a serious pace, see if BJ can keep up for 5 rounds.
