*Extensive Military background
*Super flexible
*Impressive amateur boxing background
*Both world champion kickboxer
And MMA champion
*pretty sure he holds the most records under thr zuffa banner too(most finishes, most first round finishes etc)
Maybe im partial to him cause im american, but i'd say stipe is the most proven HW athlete
*national golden gloves qualifier
*division 1 college baseball player
*division 1 college wrestler
*two time defending UFC HW champ
Mitrione will obviously gets some american sports zeitgeist votes based on him having been able to make an NFL team....rightfully so though
He was one of those high school all americans IIRC and played big ten football on a scholarship
Lesnar's NFL measurables(performed at a bodyweight of 283 pounds no less) speak for themself

*10 foot standing broad jump
*35 inch vertical
*30 bench press reps of 225 pounds
Add to that the fact he us a 2 time NCAA division 1 national wrestling champion and can do a shooting star press at almost 300 pounds....and pretty much have a good definition of what athleticism is all about
