Also, being an Iowa boy, I should mention that wrestling makes athletes that are astounding for their overall conditioning.
My experience in Judo tends to back that up. First time I did randori (sparring), I lasted one 4 minute session against a yellow belt. I couldn't do any more for the balance of the half hour session, I was shattered. I suspect the same is true of any martial art where there's constant work and contact (and if the TKD at the olympics is representitive of high level Tae Kwon Do competition, it's likely got absolutely nothing on boxing for fitness levels...)
Help msacheson & aacheson settle a dispute!
