"My mind is clearer, my sense of purpose is sharper, and my relationships are deeper," the country star tells PEOPLE

Tim McGraw may be a country megastar, but he’s also had to overcome major health struggles. Now a champion of personal fitness, the “Live Like You Were Dying” singer is going to publish a health and lifestyle book — Grit & Grace: Train the Mind, Train the Body, Own Your Life — and share his transformation story.

“I’ve gone through a physical transformation in the last 10 years, but it’s not just my appearance that has changed,” McGraw, 51, tells PEOPLE in an exclusive statement. “My mind is clearer, my sense of purpose is sharper, and my relationships are deeper. Consistent physical exercise helps me bring focus to my life and to the people who mean the most to me.”

He continues: “That’s something we all want. And I believe it’s something that is available to anyone who wants it, regardless of their level of fitness. I want this book to help people find what works for them by sharing the mental and physical approach that has worked for me.”

Grit & Grace will release on Nov. 5, 2019, and will delve into McGraw’s personal health journey. It will also share his exercise tips and mental approach so readers can improve their own wellbeing. Rather than following a set routine, McGraw explains that each person needs to create a personal vision and commit to it.

The singer did just that more than 10 years ago.

McGraw used to drink before every show to alleviate his nerves. That all changed in 2008, when he decided to cut alcohol out of his life entirely after friends voiced their concern. Instead of drinking, McGraw began to workout twice a day, he told PEOPLE in 2013.

“That’s where my workout program came into play,” he said. “It took the place of alcohol and it is really important.”

Within two years, McGraw had unintentionally lost 40 lbs.

“It wasn’t like I was trying to lose 40 pounds, I was just wanting to get healthy,” he said. “For me, it is more about feeling good and being where I want to be physically and on stage. When I am on stage in 98 degrees out there, you want to feel good. And my show isn’t stand out there and not move around.”

Since he began his workout routine, McGraw has gained all types of attention for his fit physique. But the most important change has been the positive impact on his family. From the beginning, McGraw has credited his health transformation to his wife and fellow country star, Faith Hill, 51, and their three daughters: Gracie, 21, Maggie, 20, and Audrey, 17.

“I just want to be around. I want to be around for my kids, I want to be around to see their kids, I want to be around to watch them grow up and do things,” McGraw told PEOPLE in 2015. “And I feel like the best years I have are ahead of me. I want to be ready for them. I want to be ready for whatever life comes at me later on down the road.”

Grit & Grace is a hybrid of narrative and practical, personal and prescriptive,” says Julie Will, VP editorial director of the book’s publisher, Harper Wave. “We can’t wait for his fans to go on this incredible journey with Tim, and perhaps become inspired to change their own lives in the process.”

Grit & Grace will be published on Nov. 5, 2019.
