It's hard to believe that Tyson Fury weighed 28 stone this time last year after watching the Gypsy King at Friday's weigh-in with Deontay Wilder.
In 12 months Fury has lost an incredible 10 stone thanks to intensive dieting and exercise. He looks in amazing shape compared to before.
Fury weighed in at 18st 4.5lbs - over three stone heavier than his American opponent, whose WBC heavyweight title is on the line for Saturday's fight.
Despite the weight gap, Wilder reckons Fury isn't the toughest opponent of his career and that he will win by knockout.
"[This is] definitely the most important [fight] but definitely not the hardest," he said, per BBC Sport. "I [have] fought way tougher guys than him.
"My opponent last fight (Luis Ortiz) was way tougher than him. This is just another step to get to where I want to go.
"There will be one champion [in the heavyweight division], one face, one name, and he'll go by the name [of] Deontay Wilder.
"I get to release everything that's inside of me. I can't wait. I'm going to knock him out."
Whatever the result in Los Angeles, Fury deserves endless respect for the way he's fought back from obesity and depression to make a return to boxing.
Doubts remain about whether the 30-year-old is ready for such a huge fight, but if he loses he can still hold his head high.
Ahead of the fight, boxing fans are sharing a video on social media of Fury just over a year ago weighing 28 stone to show how far he's come.
In the footage, Fury thanks Wilder for giving him the motivation to make a comeback after saying he can't do it and that he's finished.
Fury, who is panting throughout the video, ends it by saying, "I'm coming back for you," which is exactly what he's done. Check it out.
"Guess who's back, the one and only," says Fury. "Shout going out to the big Bronzed Bomber, Deontay Wilder.
"Big respect for giving me the motivation, telling me I can't do it and that I'm finished. I'm coming back for you baby, I'm coming back for you."
Fair play. Beating Wilder and winning the WBC title would go down as one of the biggest achievements in recent boxing history - it just depends on how ready Fury really is.News Now - Sport News
