Why buy a gym? I first came to Revolution in 1999, 75 pounds heavier and a smoker. When you’re the fat girl at the gym, people aren’t always kind, but I felt embraced here. Three years later I competed in my first Ironman, at Lake Placid, New York. I became a partner at Revolution in 2001 and bought it in 2006.

In 2015 you moved Revolution from 10,000 square feet in Oakley to four acres in Newtown. Why? It came from a desire to connect the mind, body, and spirit to Mother Nature. We have sand volleyball, a lake for floating yoga, a barn with turf and nets for soccer and football training, and 1.5 miles of walking paths. People spend a ridiculous amount of time indoors and they need fresh air.

Spinning was your fitness gateway drug, but what’s your favorite move now? A right jab to a focus mitt in our boxing classes. It’s fun to punch stuff and boxing is a great way to dump anxiety and fear.

What do you love to teach? Kids Ninja Club. Our American Ninja Warrior course has a warped wall, quintuple step, and ropes. I love teaching it because I have to show the kids how to do it. Our adult course is under construction.

What’s on your playlist? “Love Myself” by Hailee Steinfeld, “Let the Groove Get In” by Justin Timberlake, and “Long Way Down” by Robert DeLong, which reminds me of how far I’ve come in 17 years.

When you’re not working out…I’m listening to medical school lectures on iTunes. I’m developing curriculum to teach med students how to properly counsel their patients on exercise.
