1. She Does HIIT

“A high-intensity workout, shower, breakfast, and I'm on my way,” Dua has said. “Anaerobic interval training uses the body’s reserves of energy and, after a workout, metabolism stays elevated and continues to burn calories for hours after the workout. This is due to something called the excess post-exercise oxygen consumption (EPOC) effect. With HIIT, you not only burn a lot of calories during the workout, but because of the high intensity you will continue to burn calories as your body replaces energy and repairs muscle proteins damaged during exercise,” says ACE Fitness.

2. She is a Yogi

“Yoga fosters better sleep, which helps prevent or improve a host of health conditions linked to heart health, including depression and obesity. Yoga also encourages slow, deep breathing, which helps lower blood pressure and heart rate,” says Harvard Health. “And over time, a regular yoga practice trains your nervous system to be less reactive during periods of stress. Chronic stress is a major contributor to heart disease and many other health conditions.”

3. She Has Abs and Focuses on Her Core

Try the deadbug to work your core: “Lie down on your back with your legs up in the air, bent at the knees, and your arms pointed straight up toward the ceiling. Press your back down into the mat like you’re squishing a bug underneath your back. Lower the opposite arm and leg toward the ground without letting your back arch. If needed, start with just leg lowers until you build enough core strength to lower the arm and leg without arching. Hold for two seconds with the arm and leg extended, and slowly return to the starting position—alternate sides,” says NASM.

4. She Opts for Whole Foods

Whole foods are always the best choice. “Believe or not, but what you put in your mouth can affect whether or not your eyes sparkle. According to the National Eye Institute, the most important foods for supporting eye health are those that are rich in antioxidants like beta carotene and lutein. These peeper-friendly nutrients can be found in whole foods like sweet potatoes, carrots, and spinach,” says our sister site Eat This, Not That!

5. Carbs and Sweets Knock Her Out

"If I do eat a donut it usually puts me in a food coma!" Dua has said. "Processed foods can be so dangerous because you end up getting a lot of excess sugar, salt, and added ingredients that most people are not aware of," Isabel Smith, MS, RD, CDN, registered dietitian and founder of Isabel Smith Nutrition, tells our sister site Eat This, Not That! "There are a lot of extra calories in processed foods that are just wasteful," says Smith.
