Abililty to apply raw brain power in a logical and meaningful fashion is not necessarily correlated with the brain power itself. Also, what does chess have to do with this? Intelligence does not make one good at chess, and being good at chess does not mean that one is intelligent. The vast majority chess ability comes from practice - so what's that going to prove? This is where you are wrong. No one here is focusing on anything apart from you. Everyone else is saying that the definition of athletic also includes cardio. We are saying that explosive attributes AND cardio attributes are two factors of being athletic. Whereas you are focusing on just one. Again, no one said that being ABLE to do a marathon is athletic, apart from you. Being able to take part in an athletic event is not what makes you athletic in the sense that we are all using the word. It is the aptitude of a particular aspect makes the transition from an unathletic person competing in athletics, to an athletic person competing in athletics. There are plenty of definitions. All of which will include variations on being strong, fast, fit etc. The first two are part of what you are focusing on, the third is what everyone else is telling you to stop ignoring. There are some other definitions seemingly rooted in a much older etymology, which merely assign the label to those who take part in athletic pursuits. Neither you, nor anyone else here is using the word in that context. I half agree with this. I see his cardio as an athletic attribute, it's very good but not quite as exceptional as Calzaghe's for example. His power has to be considered an athletic attribute, which I think is being unfairly overlooked here. Froch's other strong points (punch resistance, courage, tenacity etc..) are verging into the realms of somewhat more abstract and I don't feel so strongly about those not being included under the definition of athletic - however I'm open to thoughts on that. I think half the issue is that we are using an adjective, that presumably originated to describe those who took park in athletics, to now describe people taking part in a very specific sport, with a different set of required abilities.
