I claim:

1. An abdominal muscle exercise machine comprising: (a) a body support plate having a lower surface, a front end, and having a rear end; (b) front and rear slide shafts, each havingproximal and distal ends; (c) slidable mounting means slidably interconnecting the front and rear slide shafts to the lower surface of the body support plate, the slidable mounting means facilitating alternate and forward rearward sliding motions of thefront and rear slide shafts; (d) a front "T" handle; (e) rollable or slidable mounting means interconnecting the front "T" handle and the front slide shaft, the rollable or slidable mounting means facilitating alternate forward and rearward rolling orsliding motions of the front "T" handle along the front slide shaft; the rollable or slidable mounting means positioning the "T" handle for reciprocating motions of the "T" handle alternately toward the front slide shaft's distal end and toward thefront slide shaft's proximal end; (f) at least a first rear "T" handle; and (g) rear "T" handle mounting means interconnecting the at least first rear "T" handle and the rear slide shaft.

2. The abdominal muscle exercise machine of claim 1 wherein the slidable mounting means comprise at least a first quill.

3. The abdominal muscle exercise machine of claim 2 further comprising a plurality of stabilizer bars, each stabilizer bar being fixedly attached to the at least first quill, to the lower surface of the body support plate, or to the distal endof the front slide shaft.

4. The abdominal muscle exercise machine of claim 3 further comprising a second rear "T" handle, the rear "T" handle mounting means extending the second rear "T" handle upwardly from the rear slide shaft and facilitating alternate forward andrearward sliding motions of the second rear "T" handle along the rear slide shaft.

5. The abdominal muscle exercise machine of claim 4 wherein the slidable mounting means further comprises a second quill, the front and rear slide shafts being respectively received by the at least first quill and the second quill.

6. The abdominal muscle exercise machine of claim 5 wherein the slidable mounting means further comprises means for alternately existing and permitting forward and rearward sliding motions of the forward and rearward slide shafts.

7. The abdominal muscle exercise machine of claim 6 wherein the means for alternately resisting and permitting forward and rearward sliding motions of the front and rear slide shafts comprises eye and shear pin combinations.

8. The abdominal muscle exercise machine of claim 7 wherein the first and second quills comprise lengths of square or rectangular tubing.

9. The abdominal muscle exercise machine of claim 8 wherein the body support plate has a cushioned upper surface.

10. The abdominal muscle exercise machine of claim 9 wherein the at least first rear "T" handle is rigidly attached to the distal end of the rear slide shaft.
