5 Fittest UFC Fighters

#4 Jon Jones

Jon Jones is one of the fittest fighters in the world today

Yes, Jon Jones' entire career is now under scrutiny, given that he's tested positive for illegal PEDs (Performance Enhancing Drugs) on multiple occasions over the years. However, the fact remains that -- irrespective of whether the man is on prohibited substances or not -- Jones is indeed one of the fittest athletes to have ever graced a Mixed Martial Arts cage.

Firstly, Jones' cardio is great, as the man never seems to run out of gas, no matter how many strikes he throws or absorbs inside the UFC's famed Octagon. Secondly, the strength which Jones has been gifted with, is undoubtedly legendary. Even one of his biggest enemies outside the cage -- UFC Welterweight Colby Covington -- confirmed that during their days as roommates, when they were both amateur wrestlers, Jones once literally sent a few random troublemakers flying through the air.

Love him or hate him, Jon Jones is one of the fittest athletes in combat sports today...
