John Fury has vowed to get his son Tyson Fury into shape amid the latter’s announcement that he is coming out of retirement.
The “Gypsy King” recently ended a year-long retirement that began in January 2025 following back-to-back losses to unified champion Oleksandr Usyk. While Tyson has been training in Thailand, viral footage of his physique sparked widespread fan concern, leading his father to step in with a blunt assessment of his son’s current state. The following clip shows Fury running at full speed with a tree tied to his back. However, Fury looks a lot heavier than usual. John Fury confirmed that Tyson is not in shape to fight, but has promised to get him ready for a return. The focus will be on putting on more muscle to accommodate his large frame.
“I am going to be more involved this time. Father and son. Tyson’s going to win the heavyweight championship for the third time. He’s not in fantastic shape, that’s rubbish. But he will be. I’m going to go out there and whip him back into shape. That’s the job. Head down. Work. Build a body again. Learn to move. Learn to twist and be awkward. Look like a fighter. Look like a warrior. It does matter. If it’s muscle, fine. If it’s fat, it matters. I know where he went wrong. I know how to put it right,” John Fury said
Fury has a well-documented history of massive weight fluctuations, but doing so in his late 30s is significantly more taxing. At his height (6’9″), Fury’s knees and ankles are already under immense pressure. With significant body fat and then performing high-impact explosive movements increases the risk of injury.
Rapidly cutting weight to reach “fighting shape” can lead to diminished punch resistance. We have seen this in other heavyweights; when a fighter sheds a lot of pounds in a single camp, they often enter the ring “drained,” making them more susceptible to being wobbled or knocked out by shots they would have previously shrugged off.
Coming back out of shape and facing a top-five heavyweight increases the likelihood of a knockout. History is littered with heavyweights who didn’t know when to quit—such as Bowe or Ali—whose late-career defeats could have been avoided.
