In Jackie's classes, you can expect unique, full-body movements. She focuses on single-side isolation to promote balance, and combines upper and lower body movement to target that "burns so good" feeling.  She also focuses on proper form, taking time to show you how to get the most out of every exercise. So don't be surprised if she talks, a lot.
