Carrie Underwood’s new book, Find Your Path, debuted at No. 2 on the New York Times Best Seller List in the Advice, How-To and Miscellaneous category.

In the new book, which went on sale on March 3, Carrie “shares secrets for fitting diet and exercise into a packed routine, which is based on her own active lifestyle, diet and workouts.”

“I want to be healthy and fit 52 weeks of the year, but that doesn’t mean I have to be perfect every day,” says Carrie. “This philosophy is a year-round, common-sense approach to health and fitness that involves doing your best most of the time—and by that I don’t mean being naughty for three days and good for four. I mean doing your absolute best most of the time during every week, 52 weeks of the year.”

Carrie launched a new fitness app, fit52, in conjunction with the release of her book. According to a press release, the new app is a “holistic wellness platform designed to encourage and support you on your personal wellness journey and make it easier for you to find your path to a stronger, healthier you.”

“Fitness is a true passion for me,” says Carrie. “The fit52 app incorporates what I’ve been doing myself for years, and we’ve made it easy and totally accessible for anyone that wants help to work in working out. We worked really hard to create a high-quality, user-friendly app that is designed for busy people and their busy lives. fit52 meets you wherever you are on your health journey, and I’m so proud of it.”
