"First, I wake up and go to the class, where I'm usually with my teammates. I study [at the communications center] and get schoolwork done," Dunne tells the New York Post. "[After class] I come home, eat lunch and go right to the gym, where I train for hours. I have conditioning before or after practice, which takes place at football operations. Then, I go straight to the dining hall to eat dinner. After that, I come home [to my dorm] and do my work stuff at night. Making content is definitely time consuming. There's 100s of takes and then you choose that perfect one for Instagram and TikTok. I probably take an hour or two to create content after practice. But some days I'm so busy, I can't do it all."

Dunne loves the water, and frequently posts pictures of herself surfing. "Surfing can definitely be considered a form of interval training which combines short, high intensity bursts of speed with a recovery phase, repeated during exercise training," says CSUSM professor Dr. Sean Newcomer, who researches the health benefits of surfing. "Many surfers believe that while surfing is fun, it's not necessarily a viable form of exercise on its own. This information has so far shown that surfing is very beneficial to the cardiovascular system and is a great part of a healthy lifestyle."

Dunne is fearless—the gymnast loves to scuba dive, sometimes even with sharks. "Seawater contains minerals such as magnesium, sodium, calcium, chloride, and sulfate that have natural benefits for the body," says Abe Malkin, MD. "Magnesium helps moisturize the skin and reduces inflammation. People with skin [issues] like eczema or dryness are recommended to take regular baths in salted solutions or swim in the sea."

Dunne loves to swim, especially in the ocean. "Swimming is the fourth most popular sports activity in the United States and a good way to get regular aerobic physical activity," says the CDC. "Just two and a half hours per week of aerobic physical activity, such as swimming, bicycling, or running, can decrease the risk of chronic illnesses. This can also lead to improved health for people with diabetes and heart disease. Swimmers have about half the risk of death compared with inactive people. People report enjoying water-based exercise more than exercising on land. They can also exercise longer in water than on land without increased effort or joint or muscle pain."

Dunne enjoys making new friends, and subverting their expectations of her. "I feel like people can look at me and be like, 'Oh, she always posts pictures of herself. She's that gymnast.' But, whenever I meet new people, they're always surprised, like, 'Oh, I didn't think you talk that much,' or, 'I didn't know you were this friendly.' I love meeting new people, I really do," she says.
