Sad really, the only problem with the Ab-Tronic is that it is underpowered. To beef up the system all that is needed is a V-8 motor with a good modern high voltage coil, this is standard on most modern engines. From your local auto parts store buy a coil of raw spark plug wire. Have the store crimp on the correct connector for your distributor. Measure off about 20’ of wiring and remove the insulation from about 1” of the remaining wire end. Soldier this end to a piece of metal in the shape you desire (round, oval, square, etc). Next purchase a grounding mat; you know the kind that your chair rolls around on at the office. It will have an electrical grounding cord coming off of it. Attach the grounding cord to the engine ground cable (the battery ground).
Now you are ready to use the Auto Ab-Tronic. To do so, remove one of the spark plug wires from the distributor and replace it with the wire you just made. Using a liberal amount of duct tape, tape the shaped metal end to the portion of your abs you wish to enhance. Lying on the grounding mat, have your workout companion start the engine.
Once you feel the first barrage of high voltage, Auto Ab-Tronic guarantees that you will begin snapping and writhing on the grounding mat. We also guarantee that following a program, of two ½ hour workouts each day for one month, will place you in significantly better shape than you were before starting the program. So, What are you waiting for?
