They both worked on a heavybag with boxing gloves on but also went through some grappling and jiu jitsu drills.
And Fury commented: “Nice bit of rolling around the mat.”
The Gypsy King has hinted at a switch to MMA and once said he would consider it after retiring from boxing.
But in a later U-turn, Fury confirmed he would only be interested in a striking-only match with smaller 4oz UFC gloves on.

He told talkSPORT: “No, I’ve got no real interest in grappling up and down on the floor and all that sort of stuff.
“I’m a stand-up fighting man, I don’t wrestle up and down and grab each other’s arms and sit on each other and all that.
“I’ve no interest in all that stuff – I like to stand up and fight so would I ever compete as an MMA fighter? Hell no!
“Would I compete with small gloves on in a cage in a fight? Yes. But no gripping and grappling.”

Fury, 33, has proposed UFC heavyweight champion Francis Ngannou, 35, as his crossover opponent.
The British boxing legend announced his retirement after beating Dillian Whyte, 34, in April and wants to face Ngannou in an exhibition.
And Fury’s promoter Frank Warren confirmed he would not stand in the way of talks.
Warren said: “All I can do is give him the benefit of my advice.
“All I will ever tell him is what I feel he should do but I will not say ‘you should do this’. I wouldn’t even attempt to go there.
“He’s a smart individual and whatever he decided to do will be for the benefit of himself and his family and that’s how it should be.”
