The reformer is a piece of resistance exercise equipment designed by Joseph Pilates. It consists of a platform that moves back and forth along a carriage. Resistance is provided by the exerciser’s body weight and by springs attached to the carriage and platform.

Pronunciation: re-form-er

The reformer provides finely tuned exercise resistance that allows one to work very precisely to develop good alignment, core strength, and flexibility whilst being an excellent modality of choice for a large selection of rehabilitation exercises particularly for the hips and knees.
