The latest issue of Men’s Health details Kenny Chesney’s workout routine, and how he hired a personal trainer in 2001 to get him into shape to produce the most high-energy shows in music:

Ten minutes. That’s all the time country music star Kenny Chesney needs to pump out 300 pushups. It’s a staggering number, especially when you consider it’s more than most can do in an hour. (Just try it.)

But his secret is simple: vision and focus. In fact, it’s this same clear vision and laser focus that took Chesney from singing for tips in Nashville bars back in the early 90s to landing his fourth consecutive Country Music Association Entertainer of the Year award last December. And all along, his fit, lean body has been a key part of his plan.

By 2001, Chesney had accumulated five number one singles. Only he longed not to be a country music star, but a country music brand. And that meant he needed to be the ultimate entertainer, in every aspect. That’s when he hired personal trainer Daniel Meng, owner of MUV Fitness Coaching in Nashville, Tennessee. Meng’s charge: to help the singer take his stage performance to an all-new level.

While Chesney was already in good shape, he needed to transform physically to put on what now would be the highest-energy concert in all of music. “I have to train to do my show the way I want to do it,” he says. “I’m not one of these guys that just stands there behind the microphone. I work really hard to give the fans the best possible concert.” The effort has paid off: Chesney has grossed approximately $500 million from concert ticket sales during the past 10 years.
