Mike Tyson shows off his ripped physique aged 57 as the former world heavyweight champion helps MMA star Francis Ngannou prepare for his crossover fight with Tyson Fury

Mike Tyson has shown off his stunning physique on social media as he helps Francis Ngannou prepare for his fight with Tyson Fury.

Tyson became the sport’s youngest heavyweight champion in 1986 at the age of 20.

Iron Mike established a 37-fight undefeated record before his shocking loss to Buster Douglas in 1990.

He later became world heavyweight champion again, before suffering consecutive defeats to rival Evander Holyfield.

Tyson hung up his gloves as a professional in 2005, at age 38, after back-to-back losses to Danny Williams and Kevin McBride.

However, just months after announcing his retirement, Tyson returned to the ring to stage a series of exhibitions alongside journeyman heavyweight Corey Sanders.

After the first event in Ohio was poorly received, the rest of the tour was canceled and Tyson would step away from the sport for almost 15 years.

After several years away from the ring, Tyson began sharing footage of himself training with MMA trainer Rafael Cordeiro in 2020.

Tyson lost a significant amount of weight by restarting his famous training regimen and returned to the ring in 2020 for an exhibition fight against fellow boxing legend Roy Jones Jnr.

The ‘Baddest Man on the Planet’ showed off his impressive physique on social media, posting a muscular photo with the caption ‘Still got it’.

Fans praised Tyson for maintaining his physique, with one writing: ‘Once a fighter is always a fighter.’

“So hard to keep up as you get older, huge respect,” wrote another.

The boxing legend recently formed an unlikely partnership with former UFC heavyweight powerhouse Francis Ngannou.

Tyson was approached by Ngannou on Saturday ahead of his crossover fight against Fury.

“How often do you really get involved in an immortal event,” Tyson told Mail Sport earlier this month.

‘How many times in my life will I be able to do something like that.

‘Some of the size. So of course I want to be involved and say yes to my participation.”

Tyson has worked on improving Ngannou’s striking skills, his precision and ring intelligence.
