Abstract: Exercise systems, including Pilates reformer systems, configured to provide feedback and suggestions based on a performance or an activity of the user. A system includes sensors for sensing physical aspects of and producing sensor data related to the user's performance of an exercise. The sensor data is processed to compute real-time and historical parameters. Real-time performance may be compared with historical performance and used to generate feedback and suggestions to be delivered to the user such that the user may change their activity based on the feedback or suggestions.

Abstract: An arm cord handle is disclosed that includes a flexible loop handle having a U shaped distal end and having proximal ends joined together at a common base portion. An external strap lies around and against the U shaped distal end in a storage position. The external strap has its ends fastened to the loop handle at a location spaced from the common base portion. The external strap can be deployed to an operational position away from the U shaped distal end of the flexible loop handle so that the arm cord handle is converted into a foot loop handle with the external strap positioned around a user's ankle while the U shaped distal end is positioned around the user's forefoot during exercise.
