Argentinian star Yamila Reyna is feeling very happy at the beach. Reyna, 44, shared a picture of herself smiling as she posed in the surf, wearing sunglasses and a green bathing suit. “All very nice, but the party is over!” she captioned the post. How does she stay so fit? Read on to see 5 ways Reyna stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. Mat Workout With Dumbbells

Reyna uses small dumbbells for her mat workouts. “Numerous studies have shown that strength training can play a role in slowing bone loss, and several show it can even build bone,” says Harvard Health. “This is tremendously useful to help offset age-related declines in bone mass.”

2. Diving With Sharks

Reyna loves diving in the ocean, even getting close to dangerous sharks. “A few months ago they made me live an unforgettable experience in my life, diving with more than 8 female bull sharks in their own habitat,” she says. “I remember that the previous day I did not sleep, the same day I wanted to cry, but I did not forget the words of my instructor, ‘when you see them all that fear turns into love’ and it was so!”

3. Carbs For Breakfast

Reyna enjoys carbs for breakfast—typically bagels with cream cheese and smoked salmon, or toast with jam. Having carbs earlier in the day could be a good choice for some, depending on lifestyle. “Most Americans are active early in the day and more sedentary at night,” says Kate Patton, MEd, RD, CSSD, LD. “Having your biggest portion of carbs in the evening can cause a blood sugar spike. Your body then stores the extra glucose that you didn’t use for energy as body fat.”

4. Coffee Lover

Reyna enjoys coffee, which is not only delicious but offers health benefits. “Regular daily caffeine intake — like the kind you get from your daily cuppa — is linked to a lower risk of developing Alzheimer’s disease, as well as Parkinson’s disease,” says the Cleveland Clinic. “Researchers have found that coffee drinkers have a lower risk of liver cancer and colorectal cancer — two of the leading causes of cancer deaths in the world.”

5. Outdoorsy Type

One glance at Reyna’s social media shows she is happiest when spending time outdoors, whether it’s relaxing and working out. "When you're moving your body, your heart, lungs, and muscles don't know or care where you are," says Edward Phillips, MD, assistant professor of physical medicine and rehabilitation at Harvard Medical School. "But your mind does. Some people say it's hard to rack up 7,000 steps a day walking a familiar route. But they often find they can go twice as far on a hike, especially if there's a nice vista at the destination."
