Abstract

The invention relates to an abdominal and back exerciser. A multiple-degree-of-freedom motion mechanism which is arranged on a base is connected with a seat and a seat back. An user can sit on the seat, the back leans against the seat back to form a sitting gesture, the seat back tilts backwards by the force of the upper half body tilting backwards, the multiple-degree-of-freedom motion mechanismgenerates a multi-link motion, the seat generates sequential actions of upward lifting, forward tilting and forward moving, the user forms a supine extension gesture, and then the abdominal muscle, back muscle and spine can do extension motion.

Description

technical field [0001] The present invention relates to sports equipment, more specifically, it is a sports equipment that can stretch abdominal muscles, back muscles and spine. Background technique [0002] Regarding the prior art of training abdominal and dorsal muscle groups, such as U.S. Patent 6,231,489 case.
