Mike Tyson is one of the greatest boxers in the history of the sport and a few weeks ago he announced that he was training so he could eventually get back into the ring. In a new training video shared online Iron Mike shows everyone that he still packs a mean punch. In the video the 53-year-old is throwing punches like someone half his age. Evander Holyfield, the boxer who is known for getting part of his ear bitten off by Tyson said that he too is coming out of retirement. Boxing fans around the world are hoping for a potential charity match up.
