A natural storyteller, McGraws got names for other moves, too. He does a yoga flow and dubs it Infinity. He squats deep and opens his torso to one side and calls this doing Cheyennes. He does sumo-stance squats, focusing on pushing his butt back, part of his quest for thicker legs. Those are Beyonces.

This is how the 52-year-old country-music star injects fun into a vicious 90-minute sweat he designed himself, aiming to push his own limits. I dont really get tired of training, McGraw says.Theres such a feeling of accomplishment that comes from the feeling of being my age and still being at the top of my game.

McGraw wants you in that position, too; thats why hes become one of a growing number of celebritieslike Mark Wahlberg, Tom Brady, and Chris Hemsworthleveraging global stardom to build fitness and wellness brands. McGraw creates his own workouts and partnered with exercise chain Snap Fitness to design TRUMAV, which is filled with his favorite gear (kettlebells, TRX straps, and battle ropes). His new book, Grit & Grace: Train the Mind, Train the Body, Own Your Life, describes his late-career fitness transformation.

Eleven years and 40 pounds ago, he realized hed lost control of his own fitness when he starred in Four Christmases. Hed grown up playing sports, but he was up to 215 pounds, and his daughter Gracie noticed, saying he looked big on the screen. I got out of it for a while, he says. I was in the prime of my career, and I wasnt capitalizing on it. So he ditched alcohol, burgers, and truck-stop foods and began walking in the morning.

That became a 20-minute run, and soon he was lifting weights. And he realized it was helping his music. I use my whole body to singmy legs, my butt, he says. And having more control over those things makes my voice stronger.

He also started taking his workouts on the road. The same equipment he got for TRUMAV is always at his trailer. Hours before every concert, he works out with his band, often using moves he learned from a trainer he sometimes works with, Roger Yuan. Ive learned a lot over the last three or four years.

McGraw takes pride in his transformation because it never had anything to do with the popularity contest that is celebrity. Most things in this business are out of your control, he says. What the radio is going to play, how many records youre going to sell. Control the things you can, and maybe that helps.

None of this means McGraw (or any celeb) should be your source of gym wisdom, but there is plenty that this wave of Hollywood athleticism can help you do. Guys like Tim and Chris shouldnt be viewed as fitness gurus, says MH fitness director Ebenezer Samuel, C.S.C.S. Theyve experienced success. Thats not pushing somebody else to success. Just be inspired when you see them crush their own workouts.

Back at TRUMAV, McGraw is crushing this workout. One moment hes climbing up two ropes; the next hes flipping his torso upside down on them and hoisting his legs skyward. Then hes flipping a tractor tire. He doesnt slow until he begins doing burpees and pushups.

When hes done, he feels energized. This workout is my meditation, he says.It frees things up in your head so you can get the trash out for a little while.

Break of Brawn

In a pinch for a quick sweat? Try this 20-minute basic bodyweight session, a McGraw creation. He doesnt have a name for this one, so lets call it Not a Moment Too Swoon, a play on one of McGraws big hits.

Warm up with 3 sets of 20 jumping jacks, resting 30 seconds between sets. Do the first set slowly, picking up speed with each set. Then work through the following circuit. Do each move for 40 seconds, then rest 20 seconds. Rest 1 minute after each round. Do 5 rounds.

Pushup

Situp
