Abstract
An exercise machine tension system for improving functionality and linear resistance of a Pilates machine. The exercise machine tension system generally includes an exercise machine including a carriage slidably positioned thereon. A plurality of tension units are connected between the exercise machine and the carriage for creating linear resistance as the carriage is drawn in a first direction and reverting the carriage back to its original position absent application of force. Each tension unit includes a housing, a reel rotatably positioned within the housing, a torsion spring secured to the reel, and a flexible member wound around the reel and extending out of the housing. The housing is secured to the exercise machine and the distal end of the flexible member is secured to the carriage.
