A therapeutic device, such as an exercise device, includes the principles of osteogenic repair by incorporating a loading mechanism into the exercise device. By doing so, the therapeutic device provides an increased osteogenic effect, thereby enhancing the benefits of the therapy. As an example, a exercise device includes a support surface for supporting all or part of the bodily tissue of an individual using the device. A linear or rotary loading mechanism associated with the frame or a rotational element of the exercise device drives the support surface at a selected load and frequency, thereby inducing mechanical loading of bodily tissue adjacent to the support surface sufficiently to facilitate the growth, development, strengthening, and/or healing of bone tissue. The loading mechanism may be incorporated into any exercise device, including standard exercise devices such as rowing machines, stair climbing machines, elliptical trainers, bicycles, cross-country ski trainers, treadmills, or weight trainers.
