Ermakova's dancing skills are on full display on TV dance competition Let's Dance. "Dancing is accessible to everybody. People who can't stand can use the rest of their body while seated, people who have lost movement in their arms can dance with their torso and legs," says former professional dancer Dr. Lauren Elson. "It's a way to connect to your own body, to music, and to other people. It just depends on whatever your goals are. But we know that there are so many benefits of dancing — cognitive, physical, and social — that it merits consideration by everybody."

Ermakova likes to have regular yoga sessions. "Researchers found that people who practiced yoga for at least 30 minutes once a week for at least four years, gained less weight during middle adulthood," says Harvard Health. "People who were overweight actually lost weight."

Ermakova enjoys winter sports such as skiing. "Cardiovascular or aerobic exercises also work to reduce your risk for chronic diseases, and lower blood pressure. They also help you maintain a healthy body weight," according to the University of Rochester Medical Center. "Through regular aerobic exercise like skiing and snowboarding, you lower your risk of developing conditions like diabetes and heart disease, having a stroke, and perhaps even getting cancer."

Ermakova loves long walks and hikes, especially with her mother Angela. "When you're dressed for success, hiking is a great total-body workout," says Michael Bednarz, DPM, FACFAS, a podiatric surgeon at Piedmont Healthcare. "It strengthens the large muscles in your body, while stimulating the feel-good chemical hormones of adrenaline and endorphins that boost your mood and energy levels."

Ermakova enjoys the occasional glass of red wine with her dinner. "Antioxidants in red wine called polyphenols may help protect the lining of blood vessels in the heart," says the Mayo Clinic. "A polyphenol called resveratrol is one substance in red wine that's received attention for its health benefits."
