1. She Works Her Entire Body

Underwood may be seen doing lower-body workouts in her recent Instagram post, but she makes sure to workout her entire body. Her trainer, Eve Overland, shared the singer’s workout tips with Shape. "Each workout incorporates both upper-body as well as lower-body exercises," says Overland. "Most commonly, we will work with opposing muscle groups, so she gets a lot of frequency with lower-body exercises without overworking it on any given day. This approach has contributed to her amazing strength as well as sculpted physique.

2. Fitness is a Priority

Overland tells Shape that Underwood makes fitness a large priority in her life. "Working out and staying healthy is just a way of life for Carrie. It is who she is, what she does. Carrie understands that staying strong, mobile, and conditioned is so important in all aspects of her life, on and off the stage. Working out is self care and her me time."

3. She Stays Hydrated

Underwood shared some of her wellness secrets in an interview with Women’s Health. She says that she makes sure to drink enough water each day. "One thing that I feel is so neglected in our lives is staying hydrated," she said. "It seems so simple. If you find yourself cranky ... you need to drink more water! My husband will complain about a headache sometimes and I'm like, you need to drink more water."

4. She Does Simple Workouts

When it comes to Underwood’s fitness, she believes in simplicity. Overland shared some of Underwood’s go-to moves with Shape. "She likes to stick with the basics because they work," says Overland. "Lateral band walks, leg press machine [reps], hamstring curls, and cable straight leg kickbacks are a few more go-tos because of the great pump they give you."
