HOT DAMN! TIM MCGRAW gave up drinking five years ago and replaced it with grueling physical workouts.  And the work has paid off.  Tim's 45 year old body looks as good as any 25 year old.  He should be shirtless more often.

Tim tells People 'I drank a lot from my point of view and I needed to stop. I didn't feel I had any moral high ground with my kids in the long run.' Tim replaced his alcohol high with his workouts. 'Working out is a great way to go out on stage. When I hit the stage, my adrenaline is going and I'm ready.'

Tim's adrenaline will be running as he hits the road on his 'Fast Lanes of Freedom' tour this summer, with a stop in Darien Lake.

See Tim shirtless and hear how he'd spend his perfect day in the behind the scenes video from People's photo shoot.
