Patent ID: 7789805

Claim:
A method of an athlete using a portable training apparatus to perform a flip exercise, the training apparatus comprising a base surface; an upper arcuate surface, located generally opposite the base surface, for engaging with the athlete while preforming the flip exercise when using the training apparatus; wherein a convex surface is located adjacent the base surface, and a rounded surface interconnects the convex surface with the base surface; the base surface provides a stable first position for supporting the training apparatus on a floor, and a weight distribution of the training apparatus is distributed so as to facilitate rolling movement for the training apparatus from the base surface onto the convex surface, as the athlete preforms the exercise while using the training apparatus, and, following completion of the flip exercise by the athlete, the training apparatus automatically rolls back to the stable first position so that the training apparatus is again supported on the base surface, the method comprising the steps of: a) having the athlete stand adjacent the training apparatus; b) having the athlete lunge onto the upper accurate surface of the training apparatus while preforming the flip exercise; c) the athlete causing the training apparatus to roll from the base surface onto the convex surface during the flip exercise; and d) following completion of the flip exercise by the athlete, the training apparatus automatically rolling back from an unstable second position to the stable first position in which the training apparatus is again supported on the base surface.
