Mike Tyson has a brand-new look after losing 140lbs a decade ago.

The 53-year-old former professional boxer was shirtless as he threw punches in the air for a new video shared on Weibo which was filmed in the backyard of his home.

The Hangover actor lost weigh by going vegan, he said in 2013: ‘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 clip Tyson has sculpted arms, abs and an overall slender frame as he shows off a grey beard.

He moves very fast as he throws punches in the air, ducks and then eventually pets his white fluffy dog.

Also this week it was reported Tyson is set to make his wrestling comeback to present the All Elite Wrestling champion with their official title.

The boxer – known as ‘Iron’ Mike Tyson – previously appeared as the special enforcer when ‘Stone Cold’ Steve Austin defeated Shawn Michaels for the WWE Championship at WrestleMania XIV in 1998.

And on May 23, the boxing legend will make his debut appearance for WWE’s main competitor, All Elite Wrestling (AEW), where he will be on hand to present the inaugural TNT Title to the winner of the company’s tournament.

The news was made official on Wednesday’s episode of ‘AEW Dynamite’, with the final set to see Cody Rhodes take on Lance Archer.

And AEW later confirmed in a tweet: ‘Iron @MikeTyson will be at Double or Nothing to present the #TNTChampionship to the winner of the finals between @CodyRhodes & @LanceHoyt.’

Cody – who is known as the American Nightmare, and whose father was the late Dusty Rhodes – also tweeted the news, writing: ‘It’s been a privilege to compete in this tournament.

‘It’ll be an honor to finish it.
