Andy Ruiz has wowed boxing fans with his incredible body transformation ahead of his upcoming fight with Luis Ortiz.
The Mexican-American stunned the world with a shock victory over Anthony Joshua in 2019 to become world heavyweight champion.
He made weight after his surprise victory at Madison Square Garden and would lose to Joshua in a rematch in Saudi Arabia later that year.
After a two-year hiatus from boxing, Ruiz Jr. returned with a points victory over Chris Arreola in May of last year.
The 32-year-old will face Ortiz in Los Angeles on Monday morning (our local time) as he looks to get back into contention for another shot at a world title.
Ahead of the fight, 'The Destroyer' shared a behind-the-scenes video that has fans in awe.
In the clip, Ruiz Jr. can be seen flexing his upper body and appears to have put on a significant amount of muscle.
"The best shape I've ever seen you in!
Motivating myself on my health journey!
Share it,” one fan wrote on Twitter.
Another added: "Best form I've seen Ruiz in."
While a third wrote: "Ruiz in that shape is a powerful punch for any heavyweight."
His opponent Ortiz enters the fight off the back of a sixth round knockout victory over former IBF world heavyweight champion Charles Martin earlier this year.
