Device and methods for strengthening and toning the abdominal and gluteal muscles. A seat is mounted in a fixed position on a base, and a back is pivotally mounted for movement about an axis toward the rear of the seat, with springs or elastic cords yieldably urging the backrest to pivot in an upward direction toward a raised position. To strengthen and condition the upper, lateral and oblique abdominal muscles and gluteal muscles, an exerciser rests upon the seat, with his back against the backrest, and the elastic cords or springs assist him in raising his back and also allow him to extend to the full range of backward motion while absorbing the impact of that motion. To exercise the lower abdominal muscles and gluteal muscles, the exerciser reclines on the seat, with his legs on the backrest and the elastic cords or springs assisting him in raising his legs and absorbing the impact of lowering them.

I claim: 1. An exercise machine, comprising a base having a rear cross member, a horizontally extending seat mounted in a stationary position on the base, a back support pivotally mounted on the base in front of the cross member for movement between raised and lowered positions, and a plurality of resilient elements connected between the back support and the cross member for yieldably lifting the back support toward the raised position. 2. The exercise machine of claim 1 wherein the back support is pivotally connected to the seat. 3. The exercise machine of claim 1 wherein the resilient elements are elastic cords. 4. The exercise machine of claim 1 wherein the base includes a pair of laterally extending handles which are adapted to be gripped by a person using the machine. 5. The exercise machine of claim 1 further including a headrest mounted on the back support for adjustment between extended and retracted positions. 6. The exercise machine of claim 1 further including a support attached to a rod for movement between extended and retracted positions in front of the seat. 7. The exercise machine of claim 1 further including a lumbar support which is removably mounted on the back support. 8. An exercise machine, comprising a base having a cross-member, a seat mounted on the base in a stationary position in front of the cross-member. a backrest having a downwardly extending frame toward one end thereof mounted for pivotal movement about an axis near the rear of the seat, and a plurality of resilient elements connected between the frame and the cross-member for yieldably urging the backrest to pivot in an upward direction. 9. The exercise machine of claim 8 wherein the resilient elements are elastic cords. 10. The exercise machine of claim 8 wherein the base includes a pair of laterally extending handles which are adapted to be gripped by a person using the machine. 11. The exercise machine of claim 8 further including a headrest which is mounted on the backrest for adjustment between extended and retracted positions. 12. The exercise machine of claim 8 further including a support attached to a rod for movement between extended and retracted positions in front of the seat. 13. The exercise machine of claim 8 further including a lumbar support which is removably mounted on the backrest. 14. The exercise machine of claim 8 wherein the backsupport is pivotally connected to the seat. 15. The exercise machine of claim 8 wherein the resilient elements are partially wrapped about and extend beneath the frame of the backrest. 16. An abdominal exercise machine, comprising; a frame, a seat mounted in a stationary position on the frame, a backrest pivotally connected to the seat, a backrest support pivotally connected to the seat and extending beneath the backrest, means connected between the backrest support and the frame for holding the backrest support in different angular positions relative to the seat, and means yieldably urging the backrest away from the backrest support. 17. The exercise machine of claim 16 wherein the means urging the backrest away from the backrest support comprises a compression spring positioned between the backrest and the support. 18. The exercise machine of claim 16 further including a foot rest connected to the frame for receiving the feet of a person using the machine. 19. The exercise machine of claim 18 wherein the foot rest is pivotelly connected to the frame for holding the feet in different positions. 20. An exercise machine, comprising a base having a cross-member, a seat mounted on the base in a stationary position in front of the cross-member, a backrest mounted for pivotal movement about an axis near the rear of the seat, a frame extending downwardly from the backrest and laterally of the base in a direction generally parallel to the cross-member, and a plurality of resilient elements connected between the frame and the cross-member for yieldably urging the backrest to pivot in an upward direction. 21. The exercise machine of claim 20 wherein the frame includes a cross rail which is spaced from and generally parallel to the backrest, and resilient elements are connected between the cross rail and the cross member. 22. The exercise machine of claim 21 wherein the resilient elements are partially wrapped about and extend beneath the cross rail. 23. The exercise machine of claim 20 wherein the resilient elements are elastic cords. 24. The exercise machine of claim 8 wherein the base includes a pair of laterally extending handles which are adapted to be gripped by a person using the machine. 25. The exercise machine of claim 20 further including a headrest which is mounted on the backrest for adjustment between extended and retracted positions. 26. The exercise machine of claim 20 further including a support attached to a rod for movement between extended and retracted positions in front of the seat. 27. The exercise machine of claim 20 further including a lumbar support which is removably mounted on the backrest.
