Even at 55 years of age, Mike Tyson still has that fire in the boxing ring. Footage from a recent video showcases the gruesome training schedule Tyson, or should I say, 'The Baddest Man on the Planet', goes through.'Blood sweat and tears' is the saying but isn't that true with Tyson training in this video. It would be hard to find someone who puts themselves through such a gruelling training routine as Tyson's, considering he's 55 years old. Weaving, skipping, punching, he's doing it all for someone who's achieved so much already in boxing.

'Iron Mike' was an undisputed world heavyweight champion from 1987 to 1990. His powerful punches inside the ring ranked him 16th on The Ring magazine's list of 100 greatest punchers. His knockout to win percentage during his career is 88%.Mike Tyson was one of the most terrifying fighters in the history of combat sportsConsidering retiring from the game, Tyson still loves to get involved in his old boxing routines, and the video shows that he still has it. The velocity in his punches is second to none, and even his trainer looks scared for his life despite wearing body gear. You would have to pay me quite a bit of money to step inside a ring with Tyson, as Sky Sports described him as "perhaps the most ferocious fighter to step into a professional ring."

His career in boxing is excellent; his first 19 professional boxing fights were won by knockout, 12 of which were in the first round.

Winning his first ever belt at the age of 20, Tyson holds the record for the youngest ever boxer to win a heavyweight title. ESPN placed Tyson first on their list of "The hardest hitters in the Heavyweight division."

If he keeps on training like that, I'm sure we will see 'The Baddest Man on the Planet' have one more go in the ring before he finally retires.
