The Hyatt Regency in Princeton welcomed Tim McGraw today. McGraw whose on a book tour promoting his new read Grit & Grace: Train the Mind, Train the Body, Own Your Life, stopped by the hotel to speak about it with TODAY's Hoda Kotb.

"For me it was important to set the table," explained the country singer. "Set some obstacles. Nobody's perfect."

His presence drew those near and far. People like Susan Beaver flew up from Florida for this.

"I'm probably one of the biggest Tim fans there are," explained Beaver. I heard he was gonna be here and booked my tickets."

The event was sponsored by Penn Medicine Princeton Health and was one of 2,000 at low or no cost the company is offering.

"It's a matter of being out there for the community," said Dawn Yarson an employee for Penn Medicine.

McGraw's new book follows how he stays in shape and his physical transformation. In 2008, he quit drinking and was told by his now 22-year-old daughter, that he needs to do something. The country singer then began to chase his life and started exercising.

"Walking I found relaxing," he said. "It helped put my puzzle together."

This got the 52-year-old to embark on a path to be better.

"I am an obsessively driven person," McGraw told Kotb. "When I do something I push really hard."

The father of three, will have two hour mornings and usually spends them walking while watching the news. Despite being an award-winning singer, he doesn't like to listen to music.

"I'll start counting the beats," he recalls.

McGraw also doesn't like to run due to a knee problem. Instead, he likes to squat and do yoga, while maintaining a diet filled with chicken, salad, and protein shakes.

His exercises helped him become more present, especially with his kids. He even accredits his mother for teaching him how to be a father.

"She was always there for and worked hard," he explained.

Grit & Grace: Train the Mind, Train the Body, Own Your Life will be out on November 5th.
