'This workout took place after 4 hours of training'
So it looks like to me that there is a bit of an unfair playing field here.
The boxers had already been training for 4 hours and the other guys came in fresh. I don't think that is a fair
comparison at all... Now put both of those people side by side racing and i'll be the athletes will win most
of the time.
But you'd also have to consider how well the crossfit guys would do in a boxing practice/NFL conditioning
I'd venture to guess that these guys did so well because they were good at crossfit, not because they
were better athletes than the other guys.
