Abstract: An exercise assist device includes a platform having an upper surface configured to support an individual standing thereon and a lower surface, and a base connected to the lower surface, the base configured to engage an underlying surface. The platform is cantilevered relative to the base and is movable between a first position where the platform extends generally parallel to or spaced from the underlying surface and a second position where the platform is tilted downward to engage the underlying surface. The base acts as a fulcrum to permit downward tilting of the platform from the first position to the second position when a center of gravity is moved forward to a predetermined extent relative to the base. A method of using the exercise assist device includes standing on the upper surface of the platform, bending and straightening the individual's knees while maintaining the platform in the first position.
