For the most part (to me) it seems that elite level Crossfit athletes would be the most competitive in weightlifting. There are likely numerous reasons for it but my guess is that weight class is one of them. There are few other sports that Crossfit utilizes that offer weight classes, except maybe rowing, but most people that are good at Crossfit are not tall, which is really favourable in rowing.

But I would agree with the statement. Most guys/girls have gotten much better at aerobic work the past several years while maintaining really good strength numbers.

While the cross country reference is good, even funnier wold be to see anyone try to crossover to real gymnastics. The ladies seem to cross over from there well but not a lot of men.
