Sometimes an appetizer is also the main course; such is the case with our “Mini Stability Ball” class. This 30-minute full body strength and core class utilizes a miniature ball prop to target hidden muscles and give a more comprehensive core workout. This class requires a 13-15cm miniature ball (also known as a STOTT Pilates ball) that can be purchased on Amazon, or at any sports retailer. Click HERE to view an example.
