Wave Master is a standing striking system developed by Century Martial Arts. Instead of hanging a heavybag to a ceiling, the Wave Master uses a standing base mounting the actual punching bag onto. The base is made of a hollow hard plastic form which can be filled with water, sand or ony other material as needed to achieve a stable stand.
The invention was a huge success since homes in America rarely have the structural integrity to allow heavy punching bags being mounted to ceilings or wooden walls. Wave Masters are easy to move and to store.
