Abdominal exercise device with tether assembly for connection to a resistance assembly

Abstract

The invention provides an exercise device used by a person to perform abdominal exercises, where the device comprises a weighted ball designed such that the user U can “single-hand drive” the ball through both the concentric portion and eccentric portion of the exercise movement without experiencing unwanted twisting motion of the ball while it is being held during performance of the abdominal exercises. A tether assembly includes a first tether segment and a second tether segment, both being affixed to an outer surface of the ball by a top connector assembly and a bottom connector assembly to define a first and second gaps. The top and bottom connectors are arranged 180 degrees apart and reside along a connector axis that extends through the center of the ball. A first coupler extends from the first tether segment and a second coupler extends from the first and second tether segments, respectively, for operable connection to the resistance assembly.
