TYSON FURY showed off his 15 ROUND training session with dad John and was joined by his returning brother Tommy.
The WBC champion has appeared to confirm he will fight long-time rival Dillian Whyte next, opposed to Oleksandr Usyk.
And the gruelling sessions in his private gym are well underway for the unbeaten Gypsy King.
On Instagram, Fury uploaded a clip throwing combinations on a body belt worn by his dad John.
He captioned the post: “15 rounds today for the fat man. Father son thing.”
Joining them in the ring was younger brother Tommy, 22, who is back training after suffering a broken rib.
The injury saw him pull out of his celebrity grudge match against YouTuber Jake Paul, 25, in December.
Tommy is training with big brother for his expected boxing return, targeted for March.

Fury had been at the centre of a heavyweight saga involving Anthony Joshua, Dillian Whyte and Usyk.
Whyte is currently his mandatory challenger, while Joshua is owed an immediate rematch having lost to Usyk in September.
But Middle Eastern backers were fronting talks for the pair to accept step-aside offers and allow Fury, 33, and Usyk, 35, to instead fight in a unification.
It would have seen Joshua, 32, paid up to £15m and receive a guaranteed shot at the winner.
And Whyte, 33, said to be in line for a £5m deal, would also forfeit his shot at Fury’s WBC belt.
But in a twist, ESPN report there was step-aside ‘agreement in principle’ with AJ and Whyte, until ‘parties attempted to renegotiate at the 11th hour’.
It was claimed £115million was put up for Fury to fight Usyk in Saudi Arabia in a historic, first-ever four-belt heavyweight unification.
Funds from that package would have gone to AJ and Whyte, who were believed to be on board with accepting a fee to step aside.
Nevertheless, ‘the deal fell apart’ following a moving of goalposts at the last minute.
It means Fury is now set to face Whyte with purse bids for the title defence due to take place on Friday evening.
Fury’s promotional team of Bob Arum and Frank Warren will auction against Eddie Hearn for the right to host the grudge match.
Meanwhile, Joshua is all-but confirmed for a rematch with Usyk, having been dethroned of the WBA, IBF and WBO belts.
