One of the main concepts that First Generation teacher Jay Grimes teaches is that the arms begin way down in your lower back and that finding this "back connection" to support arm movement is key to using your body correctly. In this short video, Karen explores ways to help you find the connection of arms to your back while the arms are by your sides—which feels very different than when the arms are overhead. Karen takes her student Paula from the Pull Straps on the Reformer to Chest Expansion and Thigh Stretch on the Cadillac to illustrate how the back should work with the arms. She then demonstrates how to continue the theme in more challenging exercises such as Balance Control on the Reformer and more. If you have trouble feeling where your arms connect, this class can help. Filmed at Vintage Pilates in West Los Angeles, CA.
