1. An exercise apparatus, comprising:first plate having first and second ends;second plate having first and second ends and pivotally connected to the first plate and respective first ends thereof;a spring disposed between the first and second plates and biasing the first and second plates into a first position in which the first and second plates are separated from one another;a bracket defining a generally triangular support having a base member, an upright member and an angular member interconnecting the base member and the upright member, wherein the second plate is removably mounted to the angular member; anda strap capable of mounting bracket to a support surface. 2. The exercise apparatus according to claim 1 wherein the bracket is mounted on a surface. 3. The exercise apparatus according to claim 2 wherein the surface defines a mattress. 4. The exercise apparatus according to claim 3 wherein the base member is mounted to the mattress with at least one strap that encircles the mattress and connects to the base member to minimize relative movement between the mattress and the base member. 5. The exercise apparatus according to claim 4 wherein the at least one strap extends through a pair of slots in the base member. 6. The exercise apparatus according to claim 5 wherein the base member is wider than the upright arm member to define a stable platform for supporting the bracket on the mattress. 7. The exerciser apparatus according to claim 1 wherein the angular member has a longitudinal slot therein and the first plate is mounted to the angular member for adjustable movement along the longitudinal slot. 8. The exercise apparatus according to claim 7 including at least one fastening member extending through the second plate and the longitudinal slot. 9. The exercise apparatus according to claim 1 wherein the first plate is repetitively movable relative to the first plate between the first position and a second position, and wherein each movement of the first plate from the first position to the second position defines a repetition, and further including a counter having a display for providing the user with a visual indication of the number of repetitions. 10. The exercise apparatus according to claim 1 including a dampening member between the first and second plates. 11. An exercise apparatus, comprising:an exercise module comprising:a first plate hinged to a second plate;a spring between the first and second plates and normally biasing the first plate away from the second plate into an open position;a bracket member comprising:a triangular bracket having a base member, an upright member and an angular member interconnecting the base member and the upright member;wherein the first plate of the exercise module is mounted to the angular member; anda strap capable of mounting bracket to a support surface. 12. The exercise apparatus according to claim 11 wherein the angular member includes means for adjustably mounting the exercise module thereto. 13. The exercise apparatus according to claim 11 wherein the angular member defines an angle α between the angular member and the base member, and including means for varying the angle α. 14. The exercise apparatus according to claim 11 wherein the base member includes at least one pair of slots therein and a strap extends through the slots for mounting the bracket member to a support surface. 15. The exercise apparatus according to claim 11 wherein the first plate is movable relative to the first plate between the first position and a second position, and wherein each movement of the first plate from the first position to the second position defines a repetition, and further including a counter having a display for providing the user with a visual indication of the number of repetitions. 16.
