Tim Mcgraw has given up on trying to follow his super-fit wife Faith Hill in the gym - because her work-out is too much for him.

The ripped country star works out with his bandmates two hours a day when they're on the road or working in the studio - but he admits his regime has nothing on the Breathe singer's hardcore sessions.

He explains, "I try to do her thing and I can't keep up with her. I get sore in places that I didn't know I had when I work out with her.

"The thing that she does... there are these bands that are in the ceiling; I'm not co-ordinated enough to do it... (It's the) Tracy Anderson (work-out)... and that's tough."
