The country singer and actor took to Instagram to share some inspirational photos.

Age is just a number to Tim McGraw! The 52-year-old country crooner took to Instagram to share two photos of himself to help promote his upcoming health and fitness book, Grit & Grace: Train the Mind, Train the Body, Own Your Life

First, McGraw shared a shot of himself in a fitted tank top, flashing his ripped biceps and looking determined. 

"My whole life, I’ve lived according to one key value. I guess I’ve done so from an early age, when I wanted so fiercely to get beyond my circumstances," McGraw captioned the post. "That value is, Be ready. Be primed for opportunity when it shows up, because it will come once, it will move on quick, and if you’re not ready to make the shot, your whole destiny can change in a heartbeat. Miss that moment, and you’ll live the rest of your life wondering just how much of your potential never played out."

The inspirational quote came before McGraw declared, "That’s when I decided to go from being in good shape to being in the best shape of my life. #GritandGrace." 

McGraw got lots of love from fans for his fitness pics, including actress Rita Wilson, who wrote, "Inspiring, Tim!" 

The "Humble and Kind" singer followed that post up with another image on Monday, writing, "Athleticism and sport have been intertwined into my whole way of being since an early age. It’s literally in my DNA. Even so, I lost contact with that part of myself and -- foolishly -- let the fire dwindle to the point where it almost went out."

He went on to discuss how age has factored into his fitness routine. 

"Life served me a good lesson in humility, and that led me to starting over from close to scratch. I [leaped] out of a slump at age 40, hit full stride at 45, and now at 52 it’s coming together quite nicely.

He added the hashtags #gritandgrace and #yagottabelieve and wrote on the mirror: "Ya gotta believe."

McGraw opened up to ET's Nischelle Turner back in June about his decision to take his health seriously. 

"I was not taking care of myself. I was leaning on the success that I've had," he told ET at the time. "My family is counting on me. I want to see my kids grow up, I want to be able to spend time with my grandkids. I want to take them diving and spearfishing, all those things that I want to do with my grandkids."
