Stott Pilates is a version of the Pilates method of physical exercise. It was developed by Lindsay and Moira Merrithew, with the collaboration of physical therapists, and sports medicine and fitness professionals. The most significant difference between Stott Pilates and Joseph Pilates's original method of the early 1900s is that, where the original method uses a straight spine during exercise, Stott Pilates focuses on maintaining the natural curvature of the spine.
