Dexter Jackson
One of the oldest competitors (49) , Dexter Jackson must have found the fountain of youth because he appears to be ageless. With his relentless conditioning and awe inspiring symmetry, I don’t think this old dog needs to learn many new tricks. Winning the whole thing in 2008 and barely ever falling out of the top 6, he’s definitely a force to be reckoned with. And if there was any year for a Mr. Olympia comeback – it can’t get any better than 2015 – having just locked in the record for most Arnold Classic wins of all time.
