Patent ID: 8827881

Claim:
A method of using an exercise device, comprising: providing an exercise device, including: a first portion including a first substantially planar surface and being configured to support a portion of a patient; and a second portion including a second substantially planar surface configured to support a portion of a patient, the second substantially planar surface being oppositely disposed of the first substantially planar surface; wherein an axis disposed perpendicularly with respect to the first substantially planar surface and with respect to the second substantially planar surface extends through a mid point of each of the first substantially planar surface and the second substantially planar surface; wherein the first substantially planar surface includes a diameter, wherein the second substantially planar surface includes a diameter, and wherein the diameter of the first substantially planar surface is smaller than the diameter of the second substantially planar surface wherein the exercise device includes a coefficient of friction that is sufficient to prevent movement of the exercise device when the second portion of the exercise device is in contact with the support surface and while a portion of the user's body is pivoted about the at least one point on the first portion of the exercise device; and wherein the coefficient of friction of the exercise device enables the exercise device to pivot with respect to the support surface when the first portion of the exercise device is in contact with the support surface and while a portion of the user's body is in contact with the second portion of the exercise device; placing a portion of a user's body in contact with the first portion of the exercise device, placing the second portion of the exercise device in contact with a support surface, and pivoting the portion of the user's body that is in contact with the first portion of the exercise device about at least one point of the first portion of the exercise device while the exercise device remains stationary; and placing a portion of a user's body in contact with the second portion of the exercise device, placing the first portion of the exercise device in contact with a support surface, and causing the exercise device to pivot with respect to the support surface.
