ABSTRACT:
An exercising system for exercising the abdominal muscles in which the abdominal muscles are isolated and placed "on stretch" prior to contracture comprising an exercising device having a seat with a posteriorly curved, firm back in which the user sits and secures himself and bends forward working against a progressive force resistance system using weights supported on a pulley system (three exemplary pulley systems being illustrated in FIGS. 1-3) or using a resilient, stretch material (FIGS. 4 and 5) connected by means of shoulder harness with straps to the upper shoulder portions of the user, with the user strapped into place with a seat belt. In use, the exerciser simply straps himself into the seat, puts the shoulder harness on and lies back against the posteriorly curved back which puts the abdominals in stretch. Then, by "crunching" the entire upper torso forward (as though an attempt were being made to put the face on the knees), the resisting weights are moved or the material stretched and the abdominals are exercised in isolation, with the exercise repeated as long as desired.
