Singer Carrie Underwood is fit size two, thanks to running, strength-training workouts and calorie-counting. Underwood, who follows a vegan diet, is obsessed with health-oriented phone apps to keep herself on track.
"I use my Livestrong app a lot," Underwood told USA Today Aug. 14. "I'm a calorie counter; I have been for seven years. I keep a food journal, and it has all my foods in it."
Underwood, 30, says writing down what she eats has helped her curb her late-night eating habit. The 5-foot-3 blonde beauty has been obsessed with diet and exercise since losing 20 pounds after winning "American Idol" in 2005.
Her workouts include lots of high-intensity cardio exercise such as running on the treadmill and kickboxing. She also strength-trains with five- to 30-pound weights and with resistance bands.
“My favorite thing is cardio,” said Carrie. "Cardio makes me feel good, it makes me happy. It helps the pounds melt off and it gives me so much more energy. If I can wake up and get a good cardio session in a class at a gym nearby or on the treadmill, I'm happier throughout the day."
When she's on tour, Underwood maintains her diet by buying her own food and preparing vegan meals. Underwood, who has been a vegetarian since childhood, follows a 95 percent vegan diet.
While most celebrities have their assistants do mundane chores such as food-shopping, Underwood loves grocery-shopping.
Underwood said she prefers to shop for herself because much of the food that's available to her on the road is processed and unhealthy. “I love to be at the grocery store," she said. “I don’t have a chef on tour; I make my own food on the bus."
