发明名称 ABDOMINAL EXERCISE CHAIR WITH FLEXIBLE BACK BAR AND ROTATING SEAT
摘要 An abdominal exercise chair includes two or more spinal blocks flexibly engaged together along with one or more resistance elements to provide resistance and support for a user's back as the user bends forward, backward, to the side and twists to perform exercise. One or more handles at the top of the spinal support column enable a user to engage their hands to pull and twist while keeping their spine adjacent to the spinal support.
