The 47-year-old country star shows off his ripped physique in the July/August issue of Men's Health magazine. The singer appears shirtless in the spread, with his eight-pack abs and bulging biceps on display.
"I'll be the first to admit I take it to extremes," he reveals of his workouts. "I'm not one of those people who can sorta half-ass something."
The singer says he turned to fitness after he realized excessive drinking was having a negative effect on his body and home life.
"When your wife tells you it's gone too far, that's a big wake-up call," he says of longtime love Faith Hill. "That, and realizing you're gonna lose everything you have. Not monetarily, not career-wise, but family-wise. It got to the point where my kinds were getting older, and it was way past the point that they noticed [my drinking]. And I noticed that they noticed."
McGraw is now happy and fit, with a new album scheduled for release this fall. The record is titled Sundown Heaven Town, and debuts September 16.
