Basketball with his wife better half is just part of McGraw's exercise regimen, which has been working out great lately. The singer recently showed off his ripped body in a shirtless photoshoot for Men's Health Magazine.
"It's part of a routine," McGraw said when asked about his workout secrets. "You just got to find time to do it."
McGraw has three important reasons for staying in shape -- his daughters Audrey, Maggie and Gracie.
"That's the only reason I work out -- so that I can make [my daughters' dates] nervous," McGraw joked teased. "I have a sledgehammer that I carry around when somebody comes to pick up my daughters."
McGraw can next be seen on the big screen in Tomorrowland, out May 22. This marks his ninth film, but he still gets starstruck if the movie star is big enough. He joked that he didn't have any scenes with co-star George Clooney in the movie, because it would be too much heartbreak for him.
"I just try not to stand next to [Clooney] too often," McGraw said.
