JOHN MCENROE was left baffled by Wimbledon couple Paula Badosa and Stefanos Tsitsipas's swimming pool workout routine.
The tennis stars are in a relationship and even have a shared Instagram account.
In a post from June, the pair trained together in a swimming pool with Badosa seen straddling Tsitsipas at one point.
Reacting to the clip live on the BBC, McEnroe told Clare Balding: "Training, oh is that what it is? Is that training, Clare?"
Blading replied: "I don't know. But my point is, he's in a very happy place and he's got nothing to lose here."
The on-court couple went public with their relationship only last month but Badosa was already dreaming about Tsitsipas well beforehand.

When Tsitsipas claimed Badosa had a "special dream" about him in January before they got together, she responded: "Well, I was injured in Australia. I watched his match, the final.
"Of course I had jet lag because I was in Spain. I decided to watch that match.
"Surprising, because I never dream about tennis players, but I dreamt about him that night, that we were both winning Australian Open.
"Then it was like we were having a very romantic moment, but I'm not going to explain. I'm just going to leave it there."

The sporting pair are set to play with each other in the mixed doubles at the All England Club.
But Tsitsipas admitted his girlfriend wouldn't necessarily be his first choice - as he named actor Margot Robbie as his number one team-mate.
At the Australian Open earlier this year, he said: "Australia is such a great country, I like a lot of Aussie things. One of my favourite actresses comes from Australia, Margot Robbie."
When quizzed on whether he was "making an offer" to Robbie, he added: "It would be nice to see her here one day."
Spaniard Badosa, 25, sealed a straightforward 6-3 6-3 first round victory over American Alison Riske-Amritraj on Wednesday.
But was forced to retire from her match with Ukraine's Marta Kostyuk on Friday morning with a back injury.
And boyfriend Tsitsipas resumes his match with British legend Andy Murray today, currently trailing 6-7 (3), 7-6 (2), 6-4.
