1. Sunscreen Always

Gonzalez never skips the sunscreen. “There are excellent studies that sunscreen protects against all three of the most common skin cancers: squamous cell carcinoma, basal cell carcinoma, and melanoma,” says Dr. Jennifer Lin, an assistant professor of dermatology at Harvard Medical School and co-director of the Melanoma Risk and Prevention Clinic at Brigham and Women's Hospital. “The degree of protection that sunscreen provides is directly related to the degree to which ultraviolet radiation is associated with the formation of the skin cancer. For instance, in prospective studies of sunscreen, the incidence of squamous cell carcinoma is reduced the most—as much as 40% over four years.”

2. She Loves Swimming

Gonzalez is an avid swimmer. “Swimming has long been recognized for its cardiovascular benefits,” says Seena Mathew, Assistant Professor of Biology, University of Mary Hardin-Baylor. “Because swimming involves all of the major muscle groups, the heart has to work hard, which increases blood flow throughout the body. This leads to the creation of new blood vessels, a process called angiogenesis. The greater blood flow can also lead to a large release of endorphins – hormones that act as a natural pain reducer throughout the body. This surge brings about the sense of euphoria that often follows exercise.”

3. She Plays Tennis

Gonzalez loves to play tennis. “Tennis is great aerobic exercise with a social component where you can play with friends and meet new people,” says Michael Donaworth, MD, UC Health primary care sports medicine physician and assistant professor in the Department of Orthopaedics and Sports Medicine at the University of Cincinnati College of Medicine. “It’s a lifelong sport that you can play at any age and find a competitor of similar age and skill level. Tennis is a worldwide sport, so no matter where you are, you can likely find someone who plays.”

4. Treadmill Sessions

Gonzalez incorporates treadmill sessions into her exercise regimen. “There are many benefits to adding treadmill training into your exercise routine and the convenience of the machine makes it a useful tool in commercial and home gyms,” says registered physiotherapist Sam Preston. “It’s important to vary the style of your training, as there are different adaptations and responses to each stimulus you apply to the body.”

5. Lifting Weights

Gonzalez uses weights as part of her workout routine. “As you incorporate strength training exercises into your fitness routine, you may notice improvement in your strength over time,” says the Mayo Clinic. “As your muscle mass increases, you'll likely be able to lift weight more easily and for longer periods of time. If you keep it up, you can continue to increase your strength, even if you're not in shape when you begin.”
