Underwood tells SELF that she has a really unique fitness routine. "I have a game I love for when I'm working out on my own, without a trainer. I take a deck of cards and assign each suit a body area—say, diamonds for arms, hearts for legs, spades for core and clubs for cardio. I split the deck in half and write down exercises for each suit, a different one for each half."

"I'll still set aside extra time to work out, even if it's just 15 minutes of taking a walk or getting in a little bit of cardio after a day's work. If I'm in the gym I'll switch it up between the elliptical, bike, treadmill, or swimming."
