<p>An improved exercise device comprises a rigid platform and a plurality of flexible elements attached to the bottom side of the platform in such a way as to render the platform somewhat unstable when a user stands or exercises on it, but not so unstable that the user risks falling off. The platform is of sufficient strength to support the weight of a person, as well as the weight of any exercise implements the person may be using. The exercise device thus enables the user to exercise on a slightly unstable surface, which is beneficial to the user's stabilizer muscles and sense of balance. Since the exercise device provides only a mildly unstable surface, it is safe to use as a physical therapy aid for seniors or people recovering from injuries or surgery.</p> |
