Bazán enjoys swimming in the ocean. "Exercising in natural environments has been shown to have greater benefits for mental health than exercising elsewhere," says Sergio Diez Alvarez, Director Of Medicine, The Maitland and Kurri Kurri Hospital, University of Newcastle. "This is because it combines the benefits of exercise with the restorative effects of being in nature. Swimming in the ocean is no less the case."

Bazán loves fresh fruit, especially bananas and kiwi. Kiwi is a great source of vitamin C, experts say. "Vitamin C deficiency is rare in the U.S. today, but many people still don't get the optimal amount," says Gillian Culbertson, RD. "And people with malabsorption conditions (who have trouble absorbing food and nutrients) may have lower levels of this nutrient. Eating kiwi — along with other vegetables and fruits — can help you get enough vitamin C each day."

Bazán enjoys running on the sand at the beach. "By putting in mileage on the sand, you'll put less stress on your weight-bearing joints, such as your hips, knees, and ankles, which can help decrease the risk of impact-associated injuries like stress fractures," says kinesiologist Erika Lee Sperl.

Bazán's favorite beach snack is avocado with seafood. "Avocados are an excellent source of monounsaturated fat and vitamin E, and are a good source of folate," says registered nutritionist Jo Lewin. "They also supply more soluble fiber than other fruit and contain a number of useful minerals including iron, copper and potassium."

Bazán loves to explore a new place by walking or riding a bike. "Cycling is a low impact exercise as the bike carries your weight," says fitness expert Rishabh Telang. "This makes it easier on your skeletal system and joints and makes it more possible for people from different age groups to follow an exercise form. Being a low impact exercise means that it is easier to build consistency in exercise and the intensity can be managed by how fast or slow you go."
