“I’m ready to fight Evander Holyfield” – Mike Tyson.

Boxing legend, Mike Tyson has shown off his insanely toned physique while throwing his signature fast punches in a new video

Tyson recently came out to reveal that he was coming out of retirement to stage a boxing comeback for charity and uploaded a video on his Instagram page last week showing him throwing his signature fast knock out punches.

His rival, Evander Holyfield, who Tyson famously bit off his ear in 1997 during a fight, also came out last week to reveal he was coming out of retirement, with fans optimistic the pair could stage a mouthwatering fight.

Tyson revealed he had to lose weight after making the decision to abandon meat and focus on a vegetarian diet in 2013:

He said; ‘When I was training for fights – a lot of meat, cheese, bread. I devoured everything besides pork. I used to eat a lot. As I got older I didn’t like the way I was feeling. I had a lot of arthritis, joint problems and I was morbidly obese.’ It was his wife who turned him on to going meat-free.

In this new video Tyson has sculpted arms, abs, and an overall slender frame as he showed off a grey beard.
