Bad comparison. We all know a triathlon is not MMA but it does require a high level of fitness.
A level of fitness oriented for a specific heart beat rate range throughout a specific exercice. To prepare to one thing has zero to do with preparing to another. I assure you Nick does not rely solely in his triathlon training to go in the octagon, thus the comparison is up.
Completing math problems? Not so much. Cardio vascular training has a lot more to do with MMA than math.
Some could say being a good math problem solver would help your strategy in a fight, increasing the ability to find answers for your opponent's skills and overcome your own weakness along the bout.
But to answer your question, a lot of fighters actually graduated college and are very smart so i'm sure alot of them actually could solve some pretty hard math problems
Oh, absolutely. And do some triathlon as well if they were fond of it.
And stamina is stamina, completing a triathlon gives you another thing to point too when arguing his work ethic.
It wasn't me criticizing his work ethic meaning his preparation, but I would say he has some non ethic attitude in the sport. Any high level athlete of any area can deplete his stamina to "minus zero" in less than 10 minutes if working his heart out of the range he is used to train.
PS: It could be way less than 10 minutes, actually...
