Oh, how we love the Overball! This prop has so many uses! Today we explore how it can be used to facilitate ab curls, a cornerstone of the Pilates repertoire. With the instability and the support of the Overball, it is easier for the clients to access their core musculature while learning to flex their spine forward. This is no easy task, and the Overball can be used to lean on and leverage until the client has built up enough strength to do this on their own. This is a wonderful way to introduce ab curling to new clients as well as fine tune this motion in your advanced movers.
