The apparatus of claim 1, the connecting linkage between the user support assembly and exercise arm assembly linking movement of the exercise arm assembly in a predetermined exercise path to movement of the user support assembly in said predetermined user support path;wherein the exercise arm and back pad are configured to rotate rearward and downward in said predetermined exercise path during the lower back exercise in response to the user pushing backwards on said back pad. 3. The apparatus of claim 2, wherein the back pad is pivotally mounted on the exercise arm. 4. The apparatus of claim 2, wherein the exercise arm assembly further comprises handles configured for gripping by a user during a low back exercise. 5. The apparatus of claim 2, wherein the user support assembly comprises a user support frame having a rear portion and a forward portion, a user support seat on the rear end portion and a foot plate assembly on the forward portion, and the connecting linkage is configured to rotate said user support rearward and said foot plate assembly upward and forward when said back pad moves rearward and downward during the lower back exercise. 6. The apparatus of claim 1, wherein the user support assembly further comprises an additional support which is fixed relative to the user support seat and configured to support a position on a user's body spaced from the user support seat and foot rest when the user is seated on the user support seat. 7. The apparatus of claim 6, wherein the additional support comprises a lumbar pad at a rear of the user support seat and configured to support the lower back of the user during the lower back exercise. 8. The apparatus of claim 1, wherein the user support assembly has a user support frame having a rear portion and a forwardly extending portion fixed relative to said rear portion and extending forward from said rear portion to a forward end, the user support seat being located on the rear portion of said support frame, and the foot rest being mounted on the forwardly extending portion of said support frame at a location spaced forward from said user support seat, wherein the forward spacing between said user support seat and foot rest is fixed throughout movement of said user support assembly during the lower back exercise. 9. The apparatus of claim 8, wherein the foot rest is adjustably mounted on the forward portion of the user support frame to adjust the forward spacing between said user support seat and foot rest in order to accommodate users with different leg lengths, and an adjustable locking mechanism is associated with the foot rest and configured for releasably locking the foot rest in a selected adjusted position throughout the lower back exercise. 10. The apparatus of claim 1, wherein the exercise arm assembly comprises an exercise arm pivotally mounted relative to the main frame for rotation about an exercise arm pivot axis. 11. The apparatus of claim 10, wherein the user support assembly is pivotally mounted relative to the main frame for rotation about a user support pivot axis, and the back pad is pivotally mounted on the exercise arm for rotation about a back pad pivot axis spaced from said user support pivot axis. 12. The apparatus of claim 1, wherein said connecting linkage comprises a multi-part connecting linkage. 13. The apparatus of claim 12, wherein said connecting linkage comprises a control link pivotally connected between said user support assembly and said main frame and at least one pivot link between said exercise arm assembly and said user support assembly, whereby movement of said exercise arm assembly in an exercise path corresponding to a lower back exercise simultaneously moves said user support assembly in said predetermined user support path. 14. The apparatus of claim 1, wherein the user support assembly is pivotally mounted relative to the frame for rotation about a first pivot axis, and a vertical gravitational center line which extends through the first pivot axis extends through the user support assembly through at least part of the lower back exercise. 15. The apparatus of claim 14, wherein the vertical gravitational center line extends through the user support assembly throughout an entire lower back exercise. 16. The apparatus of claim 1, wherein the connecting linkage comprises at least one connecting link pivotally connected between the user support assembly and the main frame. 17. The apparatus of claim 16, wherein the connecting linkage further comprises a pivot link between the user support assembly and exercise arm assembly, the pivot link and connecting link being configured to move the user support assembly in a predetermined compound movement path during the lower back exercise. 18. The apparatus of claim 1, wherein the main frame has a pair of spaced, generally upright portions, the exercise arm assembly is pivotally connected between said upright portions for rotation about a first pivot axis, and the user support assembly is pivotally linked to the exercise arm assembly for rotation about a second pivot axis, the second pivot axis being spaced from the first pivot axis and parallel to the first pivot axis. 19. The apparatus of claim 18, wherein the user support assembly has a rear end portion and a forward end portion, and the connecting linkage comprises a connecting link pivotally connected to the user support assembly at a first location for rotation about a third pivot axis and pivotally connected to the main frame at a second location spaced below the first location for rotation about a fourth pivot axis, whereby rotation of said exercise arm assembly about said first pivot axis rotates the rear portion of said user support assembly rearward and the forward portion of said user support assembly upward. 20.
