1. Horseback Riding

Martínez loves horseback riding, which offers many physical and mental health benefits. “Anyone who has ever slung a leg over a horse’s back, held the reins and ridden into the sunset (or at least around a corral) knows the sensation,” says the American Heart Association. “Yeah, that one. The one that makes you sit tall, sit proud, feel one with another living being. The one that fills your nostrils with the smell of hay or of pine trees; that fills your spirit with hope that anything is possible, and fills your mind with wonder at the majestic beast supporting you. As an added bonus, you’re also guiding yourself to a longer and healthier life. You’re bonding -- with yourself and your horse, of course, but also with nature. Because in a world filled with treadmills and weight machines, nothing beats being outside.”

2. She Lifts Weights

Martínez lifts heavy weights which not only help give her a strong and toned physique, it’s good for bone health, too. “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. Activities that put stress on bones can nudge bone-forming cells into action. That stress comes from the tugging and pushing on bone that occur during strength training (as well as weight-bearing aerobic exercises like walking or running). The result is stronger, denser bones.”

3. She Plays Guitar

Martínez loves her guitar—playing an instrument is like a workout for the brain, experts say. “It engages every major part of the central nervous system,” says John Dani, PhD, chair of Neuroscience at Penn’s Perelman School of Medicine, tapping into both the right and left sides of the brain. “Recent studies suggest that music may be a uniquely good form of exercising your brain. Fun can also be good for you.”

4. She’s a Dancer

Martínez is a skilled performer, and dancing is part of her lifestyle. “We know that movement is good for everyone,” says Emily Sandow, supervisor of dance physical therapy at NYU Langone’s Harkness Center for Dance Injuries. “A healthy lifestyle is integrating the mind, body and soul relationship, and dance has all of those characteristics. Everyone can do something, even if it’s just you just tapping your foot. Everyone can do something where they can move their body to music, and that’s really valuable.”

5. Fresh Orange Juice For Breakfast

Martínez is not fussy about her breakfast—she enjoys fresh orange juice and a cup of coffee. “A clinical study reported that a daily glass of orange juice for four weeks has a blood thinning effect and may reduce blood pressure,” says registered nutritionist Nicola Shubrook. “Further studies suggest including citrus in the diet protects against cardiovascular disease by reducing oxidative damage and inflammation, and improving the health of blood vessels.”
