1. She Does Pilates

“I work with Fluidform [Pilates] and have been doing it at home now for some time. [Kirsten King’s] whole philosophy as a Pilates teacher is about poise and lengthening,” Pia revealed to Body + Soul about her go-to workout. She recently posted a photo on Instagram of herself at the studio. "It's always just joy,” she captioned it.

Whitesell loves hiking. In this recent set of photos she hikes a cave trail in Sydney. "Adventure time," she captioned it. "The faster, farther and more frequently you walk, the greater the benefits,” the Mayo Clinic says about hiking. “For example, you may start out as an average walker, and then work your way up to walking faster and walking a mile in a shorter amount of time than an average walker, similar to power walkers. This can be a great way to get aerobic activity, improve your heart health and increase your endurance while burning calories.”

3. She Spins

Pia loves spinning, on exercise bikes and outdoors. In this photo she goes for a ride in Sydney. "A single exercise session that gets your heartrate up can lower blood pressure, improve sleep, lower anxiety and improve insulin sensitivity on the day you do it. Other benefits, like lowering your risk of many chronic diseases and cancers, start adding up within days or weeks of regular physical activity," says the Mayo Clinic.

4. She Takes Infrared Saunas

“I have an infrared sauna, so I use that a lot. And I have an unheated pool, so I go from the sauna to the pool,” Pia told Body + Soul. “I really do love infrared – you can have a moment of escapism. It’s like, ‘Boys, I’m in the sauna. Do not disturb.’”

5. She Works Out at the Gym

Pia also makes sure to exercise. “I switch it up with going to the gym and listening to hip-hop while running on the treadmill or on the step machine,” she told Body + Soul. Physical activity is anything that gets your body moving. Each week adults need 150 minutes of moderate-intensity physical activity and 2 days of muscle-strengthening activity, according to the current Physical Activity Guidelines for Americans.

6. She Surfs

Pia, who lives in Malibu with her husband, loves surfing. According to the Australian government’s Better Health, surfing provides many health benefits including cardiovascular fitness from paddling, shoulder and back strength, which also strengthens from the paddling, and leg and core strength. “Once you’re standing up on the board, strong legs and a strong core will keep you up,” they say.

7. She Prioritizes Her Mental Health

Pia prioritizes her mental health. What is her secret? “Being in the ocean and outdoors as much as possible with my boys. Whether it’s at a basketball court or going for a coastal walk, racing up the street. I have these boys with this insane athletic ability. They smash me!” she told Body + Soul.
