Tim McGraw likely has the best abs in country music, and the singer spent St. Patrick's Day (March 17) proving that time spent in the gym will result in some serious payoff ... and superhero powers.

McGraw apparently spent his holiday at the lake, onboard a crazy contraption that allowed him to fly high above the water. Even more impressive, a photo shared on social media shows that the superstar doesn't require help to balance; in fact, his hands are relaxed by his side and he looks like he's flying as he takes in the beautiful scenery around him.

Of course, McGraw is some nice scenery as well, wearing only a bathing suit!

McGraw's abs, of course, are as honed as ever. The 'Lookin' for That Girl' hitmaker has certainly worked hard for his sleek physique. He avoids carbs and beef and is an avid fan of CrossFit, which he explains is great for keeping things interesting.

“That’s one of my favorite things to do, because I have a short attention span, so I can switch exercises really quickly if I get tired of one,” he admits. Boredom is often a problem for those who work out -- or try to work out -- so that seems like a great method for those who find the process uninteresting.

While corned beef and cabbage was consumed by many on St. Patty's Day, the singer probably wasn't noshing on the typical celebratory meal. But it's worth missing out for those abs! McGraw is currently working on an emotional new album, which is said to street in May. He's also gearing up to kick off his Sundown Heaven Town Tour, which stops in 30 cities this summer.
