Tim McGraw has become known for his intense workouts, even on the road, and it turns out they’re so strenuous most people who try to work out with him come up short. McGraw tells his label, Big Machine, that though he usually has a bigger group when the workout begins, they gradually start to fall off as the hours go by.

“It usually starts out with 10 or 15 people and about an hour and a half, two hours into it, it ends up being about five and then it finally dwindles down to one or two left,” he explains with a laugh.

What makes the workout so difficult? McGraw says to stay fit, he incorporates a lot of the high-intensity strength training CrossFit touts, combined with a ton of cardio. He adds that he can do a lot of it without the comforts of a home gym when he’s on the road.

"It’s a lot of CrossFit stuff. We use ropes and chains and all kinds of things and run a lot. I do a lot of cardio, that’s the main thing,” he shares. "I work out at home in my gym, do standard stuff. You know, there’s a lot of stuff I can do without having a gym or anything — just pushups and crunches and running."

The artist says he doesn’t mind working out on the road, though. In fact, he prefers it because of the company.

“It’s easier on the road. A lot of people say it’s hard to work out on the road and you’d rather be at home, but for me it’s easier on the road because we have five or six guys in the band and in the crew that work out with us,” he says of the ones who have what it takes to keep up.

McGraw just released a new single from his record Damn Country Music titled “How I’ll Always Be,” a rolling nostalgic ballad that also looks toward the future, reflecting on the attributes that make him who he is.
