Tim McGraw gave up alcohol after realising he had no "moral high ground" with his children.
The country singer and his wife Faith Hill have three daughters, Gracie Katherine, 15, Maggie Elizabeth, 14, and Audrey Caroline, 11. Family life is the most important thing to the stars, who try not to be apart for more than three days.
Tim quit drinking five years ago after considering the message he was giving his children.
"I drank a lot from my point of view and I needed to stop," he told People magazine. "I felt quitting was something I needed to do. I didn't feel I had any moral high ground with my kids in the long run."
After deciding to leave alcohol alone, the 45-year-old star began to focus on exercising. He now works out regularly, boasts an eight-pack of stomach muscles and insists his regime helps him give his performances his all.
"Working out is a great way to go out on stage," he explained. "When I hit the stage, my adrenaline is going and I'm ready."
Tim's latest record Two Lanes of Freedom hits stores next month and he is promoting it with a tour later in the year. He is looking forward to hitting the road and sharing his new sounds with fans as they are so personal.
"I'm in a good place right now," he said. "I really feel like this new album is not a culmination of the things I've done, it's a new beginning of the things I am going to do. I want to enjoy my career and having my family. I have a busy life, but it is a fulfilling life."
Tim and Faith married in 1996 but his drinking caused a lot of problems in their marriage. He has previously admitted he doesn't know what would have happened to him had Faith not been his wife.
The star learnt to text message after Faith got angry when he would call her and sound drunk. He realised he needed to get help when he started to show he was inebriated even via texts.
"Right before I got married, I was a full-fledged rock star... [If I hadn't met Faith], I'd be dead...," he previously said.
"I would have partied too hard. I might have caught myself somewhere along the way and put the brakes on. I don't know if I would have gone [to rehab]; I don't think I could have been talked into that during those times."
