Cherem is a big fan of resistance training. "Strength training may enhance your quality of life and improve your ability to do everyday activities," says the Mayo Clinic. "Strength training can also protect your joints from injury. Building muscle also can contribute to better balance and may reduce your risk of falls. This can help you maintain independence as you age."

Chelem is careful to keep her skin well-exfoliated. "Dry brushing unclogs pores in the exfoliation process. It also helps detoxify your skin by increasing blood circulation and promoting lymph flow/drainage," says dermatologist Shilpi Khetarpal, MD. "Do not use dry brush or cloth on skin that's broken. This includes cuts, scrapes, lesions, sores or burned skin, including sunburns. Don't ever brush over areas of infection, redness or general irritation, inflammation, cellulitis or skin cancer. Stop dry brushing if skin becomes irritated or inflamed."

Chemen likes using a mat for stretching exercises. "A lot of people don't understand that stretching has to happen on a regular basis. It should be daily," says David Nolan, a physical therapist at Harvard-affiliated Massachusetts General Hospital. "The areas critical for mobility are in your lower extremities: your calves, your hamstrings, your hip flexors in the pelvis and quadriceps in the front of the thigh."

Cherem is not afraid to build muscle by lifting heavy weights. "Such exercises also improve glucose metabolism, enhance maintenance of healthy body weight, and help improve cardiovascular risk factors such as blood pressure," says I-Min Lee, MD, professor of epidemiology at Harvard T.H. Chan School of Public Health. "All these factors lead to lower risks of cardiovascular disease, cancer, and diabetes, which lowers mortality risk."

Cherem enjoys mixing up her workouts, sometimes adding boxing exercises to her workout regimen. "This kind of boxing has many health benefits, because it constantly requires you to think, change your position, and change your posture," says physical therapist Linda Arslanian, director of rehabilitation services at Harvard-affiliated Brigham and Women's hospital. "You're swinging your arms, moving the muscles of your arms and shoulders, increasing your upper-body strength. And when you're in the boxer crouch with a wide stance, with your knees slightly bent, you're strengthening your core muscles, back, and legs."
