Patent abstract
A swing rotary fitness apparatus is described. A swing base is axially disposed at a center of a bracket having a pair of handles. A pound-force adjuster is disposed between the swing base and the bracket, and elastic elements for restoration are disposed between the swing base and the bracket. In addition, a rotatable seat is disposed on the swing base. When a user rides on the seat, the user exerts a force by lumbar muscles, so as to generate a circumferential motion of synchronous swing and rotation, which increases amplitude of twisting lumbar muscles greatly and thus improves an effect of exercising the waist.
