Staying fit isn’t just about hitting the gym. Evelin promotes an active lifestyle, which can be evidenced by her Instagram feed. Some of her favorite outdoor activities include surfing, hiking, hang gliding, and walking on the beach. "The synergistic combination of exercise and exposure to nature and thus the ‘great outdoors’ could be used as a powerful tool to help fight the growing incidence of both physical inactivity and non-communicable disease," says one study.

2. Drink Lots of Water

Evelin understands the importance of hydration. In addition to water, she keeps her thirst quenched and electrolytes restored with help of coconut water. Here she is drinking out of a coconut on the beach. "As a casual beverage, coconut water is considered safe. Coconut water does have calories — 45 to 60 calories in an 8-ounce serving. Weighing the pros and cons, plain water is still the smart choice," says the Mayo Clinic.

3. Try Supplements

“A challenge worth doing. Go ahead and do it, tag me in your stories of you talking about what is your favorite part of your body. We all deserve to feel beautiful and sexy. Much love,” Evelin said in a since-deleted video, per Showbiz CheatSheet. “I want you to go to a mirror, look at yourself, and find out what is the favorite part of your body. What makes you feel sexy and makes you feel pretty. Mine, for example, are these dots on my chest,” she says in it. “If we feel pretty outside we feel pretty inside, if we feel pretty inside, we feel pretty outside."
