ANDY RUIZ JR looks a far cry from the bloated fighter who lost his rematch to Anthony Joshua.
The Mexican was slammed for piling on the pounds when he conceded his heavyweight titles to the Brit a year ago.
But he has shown off his terrific body transformation as he plots his return to the ring.
Ruiz Jr, 31, appears to have ditched the partying and Snickers bars to get himself back in fighting shape.
‘The Destroyer’ revealed his intentions to get back among the best by parting ways with his former trainer in favour of Eddy Reynoso, who also trains Canelo Alvarez.
In a video posted on Instagram, Ruiz Jr can be seen being put through his paces and launching the left hooks that gave AJ nightmares in their first meeting.
Alongside the video he wrote: “Working hard getting ready for whoever is next. Thanks to God we are on the right track.”
Ruiz Jr confirmed he has dropped 20lbs although admitted he has been worked to the core.
He said: “It’s hard man. I have never done this in my whole life.
“Never lift weights, never had a physical trainer like they are doing… It’s time to execute, time to get it back, time to work hard.”
With old foe AJ set to face Tyson Fury next year, Ruiz Jr is still seeking out his next opponent.
But Matchroom promoter Eddie Hearn confirmed it could come in the form of Dillian Whyte.
Speaking to Sky Sports News, Hearn said: “We will be reaching out to other players in the heavyweight division to see if they fancy it.
“I’d love to make Ruiz Jr vs Whyte, Wilder vs Whyte, Ortiz vs Whyte.”
