Don't sign up Brantley Gilbert for cardio. He will definitely work out with Tim McGraw when the two head out on tour together in May, but Gilbert told me Tuesday (April 23), "Cardio's not really my deal." After McGraw asked Gilbert recently if he was ready for the tour and the three-hour CrossFit workouts, Gilbert had to break the news. "I don't do the CrossFit. I'll lift all day long with him. I'll flip a stupid tire. But I ain't running," Gilbert said. "I said, 'Dude, I had a CrossFit trainer for two weeks, and I fired him.'" What Gilbert will do while he's on the road this summer is visit more food banks across the country to help pack meals and spread awareness about the hunger crisis. His work with Outnumber Hunger is an ongoing effort that Gilbert tries to fit in at every stop where they have time between soundcheck and showtime. And he thinks McGraw will be cool with that. Gilbert already has a bond with McGraw because they have a lot in common. "I'm getting married to someone [Jana Kramer] who is in the business, and Tim knows all about that. He's had some advice for me," Gilbert told me. "Good guy, good friendship."
