4: Jon Jones
During his infamous suspension in 2015 following a hit-and-run incident, Jon Jones posted videos where he was powerlifting mind (and bar) bending weights. It seemed that the then number one pound-for-pound fighter in the world had turned to the sport to channel his energies during the lay off. For a man who admittedly has chicken legs and was so skinny that his college football coach nicknamed him "Bones", feats like this 600-lbs deadlift are truly astonishing:
But sadly, Jones' return has been stained by multiple doping violations and his legacy could be all but blackened. He was recently fined $205,000 and had his fighting license revoked by the California State Athletic Commission until he is cleared by USADA.
