Abstract
The present invention discloses a method for strengthening the abdominal musculature. The method primarily copmrises isometric contraction of the abdominal musculature while the operator is seated in a specific position. The positioning entails a generally seated position of the operator in which the forearms are generally orthogonal to the arms, the arms are generally parallel to the thoracic spine, the legs are extended, the hip is flexed, the thoracic and lumbar spine are slightly flexed. While in this position, the operator contracts the abdominal musculature by pulling with the hands on a tow line, and pushing the feet against a foot stop, involuntarily tensing the abdominal musculature. Additional strengthening of the abdominal musculature is achieved by positioning the pelvis on the seat such that the pelvis is posteriorly rotated, by allowing the chest to move forward against a chest restraint, and by taking a breath and holding it by doing isometric contractions of the abdominal musculature.
