A system for assisting in the performance of passive stretches includes a stretching device and a control mechanism. The stretching device includes an inflatable component. The control mechanism enables a user to control the degree of inflation of the inflatable component. The stretching device may optionally include one or more user contact surfaces attached to an outer layer or formed within an outer layer. The system may also include a support for supporting the stretching device at a particular height. The support may compressively hold the stretching device at the particular height when the inflatable component is inflated.
