1. She Soaks Up the Vitamin D

Roitman is often in the sun. “Many older adults don't get regular exposure to sunlight and have trouble absorbing vitamin D. If your doctor suspects you're not getting enough vitamin D, a simple blood test can check the levels of this vitamin in your blood,” says the Mayo Clinic. “Taking a multivitamin with vitamin D may help improve bone health. The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years.”

2. She Does Squats

Roitman does squats to stay fit. “Domingo con actitud de lunes por? el final me describe 👍🏻,” she captioned one video. “To do a squat, stand with your feet slightly greater than shoulder-width apart and your toes pointing ahead. Slowly descend, bending through the hips, knees and ankles. Stop when your knees reach a 90-degree angle. Then return to the starting position. You'll feel tension in your legs and buttocks,” Nicole Campbell tells the Mayo Clinic.

3. She Works With TRX Bands

Roitman adds resistance to her training using TRX suspension bands. “Suspension trainers provide an inexpensive, complete full-body workout and use minimal space. Most trainer’s kit comes with a set of bands along with foot anchors and handles to accommodate different exercises. These resistance exercises help you develop flexibility, balance, strength, and joint stability all at the same time. Anyone can use TRX systems,” says the Cleveland Clinic.

4. She Hits the Punching Bag

Hitting the punching bag is a good way to relieve stress, like any physical activity. “Physical activity may help bump up the production of your brain's feel-good neurotransmitters, called endorphins. Although this function is often referred to as a runner's high, any aerobic activity, such as a rousing game of tennis or a nature hike, can contribute to this same feeling,” says the Mayo Clinic.

5. She Swims

“Swimming uses all the muscles in the body so whether you swim a gentle breaststroke or hammer butterfly, you will get a full body workout. Plus, exercising in water makes your body work harder so 30 minutes in a pool is worth 45 minutes of the same activity on land,” says Swimming.org. “Just 30 minutes of swimming three times a week alongside a balanced, healthy diet and lifestyle is one of the best ways to stay fit and healthy and maintain a positive mental outlook. Do it with friends, and it’s even more fun!”
