ABSTRACT:
This trunk rotation device uses dynamic movement of one's body such as, shoulder, hip, knee, back, thigh, and abdominal musculature. The device provides a method for exercising the spinal column and the muscles of the torso, including those in the abdominal lumbar and thoracic regions involving rotational torque. In a preferred embodiment, the device is a golf exercise and flexibility apparatus. The golf exercise apparatus provides resistance to a golfer during a golf swing to strengthen and condition the muscles of the axial skeleton of the golfer in a functional posture.
