“And she said: ‘Oh, if you're just going to go and play golf, I don't want that’.
"I was like: ‘No, no, I'll get myself in the gym, make sure I stay in shape’.
“I went to the gym three of the first four days after I stopped, worked really hard, and then went up to Scotland for a couple of days for a holiday, and haven't been back since.
“It's been five weeks I've not been in the gym, longest ever for me probably.

“But we obviously have like loads of the sport drinks have got lot of calories in them, and I only really drink water and coffee now.
“So I don't know, I think just less calories and probably loss of muscle.
"I've lost about 11, 12 pounds. It's a lot. I was expecting the opposite to happen. It's about five kilos, yeah.”
Murray joined fellow Scot and Ryder Cup star Bob MacIntyre as well as Jimmy Anderson and Anton Du Beke, who was his mum Judy's partner on Strictly Come Dancing, the two-time Wimbledon champion admitted he still has some way before he can call himself a pro.

He said: “I'm obviously getting to practise a lot more than the average person.
“I obviously played a bit when I was younger, and if I can get the right sort of lessons and practise the right things, then yeah, I've got a chance of doing that I think in a couple years.
“Will you the lessons have made a huge difference. That's been the most important thing for me. I used to go down to the range and hit lots of balls, and I could hit a few good ones.
“But if you have a fundamental flaw in your swing or what you're doing, it doesn't matter how many balls you hit on the range. So getting lessons and practising those things is helping.”
