Andy Ruiz Jr. has shown off his remarkable body transformation as he looks to return to the ring.
Ruiz Jr. hasn't fought since his majority draw against controversial American fighter Jarrell Miller last August.
He fractured his hand in his stalemate with Miller and has been sidelined since their Los Angeles bout.
But Ruiz Jr. is working hard behind the scenes and is plotting a big boxing comeback.
That's judging by his social media activity as he took to Instagram to show off his new physique.
He shared a topless selfie on his Instagram story, accompanied with the caption: "The diet is hard. Slowly but surely. Work in progress."
Considering he has been out of action for eleven months, the 35-year-old stunned boxing fans with his current physique.

A second added: "Good to see him focused now."
When is Andy Ruiz Jr.'s next fight?
Ruiz Jr.'s career has stagnated since rising to prominence following his fights against Anthony Joshua.
He has only fought three times since losing the unified world heavyweight titles to Joshua in 2019, having stopped the Brit to capture the world heavyweight belts.

"It was crazy, I hadn't fought in two years but I would love to do a rematch," he said.
"Let's do it again. It was pretty exhausting. You've got a 300lb man coming at me throwing and throwing.
"I think I did pretty good for me doing the two-year long layoff. Like I said, let's do it again.
"I hurt my right hand, you guys can see the bone right here. Let's do it again."
Ruiz Jr. is still one of the biggest names in the heavyweight division and is likely to land a huge fight when he does eventually return to the ring.
