Tim McGraw is in the best shape of his life. Even his six pack has a six pack.
Though he's always been into fitness, he admits he slacked off for awhile. He got back to it in his early 40s and says it has made everything in his life better.
He tells Men's Fitness, "I just realized how much it raised the bar on everything that I did. It raised the bar on my career. It raised the bar on my relationships with my friends. It just made me feel better, gave me a better mental outlook on everything that I was doing."
Tim's just signed on with Snap Fitness to design a line of fitness clubs called TRU MAV Signature Clubs.
