Our Story
Center City Studio classes feature a mix of yoga and other assorted gentle movements. And in 2025, additional 1-on-1 training and small group training opportunities, including Pilates, yoga, stretching, and more.
Located on the Ashman Circle, Center City Studio shares a studio space with Jazzercise Midland. Our classes nicely complement our Jazzercise classes and members may participate in one, or both programs.
Our goal is to keep you moving - one way or another! If you're ready to experience a more flexible body, come see us! We believe that incorporating gentle movement into your regular routine will improve your flexibility, strength, mobility, and balance – and ultimately improve your quality of life.​
