An improved rock climbing simulator that uses an adjustable fluid resistance apparatus coupled to an axle of a rotating climbing surface to control the rate of rotation of the climbing surface and thus the perceived climbing speed experienced by the climber. The fluid resistance apparatus is structured to control the rate of rotation of the climbing surface, and hence the perceived climbing speed, regardless of the weight or position of a climber on the climbing surface.

Having thus described the invention, what is claimed is: 1. A climbing exercise apparatus for a user comprising: a generally planar and rigid exercise surface of sufficient size for the user to interact therewith in a simulated climbing exercise, said exercise surface being generally vertically oriented and bounded by a perimeter and arranged for rotation about a central axis, said central axis being generally perpendicular to said exercise surface; a drive mechanism connected to said exercise surface and having an output shaft, said drive mechanism for converting movement of said surface into rotational movement of said output shaft; and a resistance mechanism connected to said output shaft, said resistance mechanism having a positive displacement pump for connection and rotation by said output shaft, a throttle, a circulating loop hydraulically connecting said pump and said throttle, and a circulating fluid disposed within said circulating loop, said throttle being selectively adjustable and acting upon said fluid whereby said resistance mechanism, once adjusted, limits the rate of motion of said exercise surface to a desired maximum rate when the user interacts with said surface. 2. The apparatus of claim 1, wherein said movable surface is a generally circular planar structure having a diameter disposed for rotation about said central axis and said central axis is aligned with said output shaft. 3. The apparatus of claim 2, wherein said exercise surface is rotatable in either of two opposing directions about said central axis. 4. The apparatus of claim 3, wherein said diameter is on the order of eight to ten feet. 5. The apparatus of claim 4, wherein said movable surface further comprises a plurality of protrusions shaped and arranged to facilitate simulated climbing by the user. 6. The apparatus of claim 5, wherein said movable surface may be aligned at an angle relative to a vertical plane. 7. The apparatus of claim 6, wherein said angle ranges between zero and approximately 15 degrees in either direction from vertical. 8. An exercise apparatus simulating climbing on a surface comprising: a frame for supporting said apparatus; a generally planar and rigid climbing surface bounded by a perimeter of sufficient size for a user to interact therewith in a simulated climbing exercise, said climbing surface being oriented substantially vertically; an axle supported by said frame, said axle connected to said climbing surface and oriented generally perpendicular thereto thereby enabling said climbing surface to rotate in either of two opposing directions about said central axis; and a resistance mechanism connected to said axle, said resistance mechanism having a positive displacement hydraulic pump for circulating a working fluid in a closed loop responsive to rotation of said axle and an adjustable throttle disposed in said closed loop for regulating a rate of fluid flow in said loop, wherein a rate of rotation of said climbing surface, when said apparatus is in use, is limited to a desired maximum rate by adjustment of said throttle when the user interacts with said climbing surface. 9. The apparatus of claim 8, wherein said climbing surface is a generally circular structure having a diameter centered disposed for rotation about said axle. 10. The apparatus of claim 9, wherein said diameter is on the order of eight to ten feet. 11. The apparatus of claim 10, wherein said climbing surface further comprises a plurality of protrusions shaped and arranged for use as climbing holds. 12. The apparatus of claim 11, wherein said climbing surface may be aligned at an angle in either direction relative to a vertical plane. 13. The apparatus of claim 12, wherein said angle ranges between zero and approximately 15 degrees. 14. A method for controlling the motion of a climbing surface on an exercise apparatus comprising the following steps: providing a generally rigid planar and vertically oriented movable climbing surface bounded by a perimeter, said climbing surface being of sufficient size for a user to interact therewith in a simulated climbing exercise and rotatable in either direction about an axis normal to the planar surface; providing an axle connected to the surface and disposed on the axis; providing a resistance mechanism connected to the axle, the resistance mechanism having a circulating fluid and a throttle, the throttle disposed to regulate the flow of fluid in the mechanism to limit rate of rotation of said surface; allowing a first user to engage the climbing surface in a manner simulating climbing, the weight of the participant tending to cause the climbing surface to rotate; circulating the fluid by rotation of the climbing surface transferred via the axle to the resistance mechanism; and adjusting the throttle to provide a resistance to rotation of the climbing surface until a desired rate of rotation of the climbing surface is achieved. 15. The method of claim 14, further comprising the step of adjusting the throttle to increase resistance to achieve a slower climbing speed. 16. The method of claim 14, further comprising the step of adjusting the throttle to decrease resistance to achieve a faster climbing speed. 17. The method of claim 14, further comprising the step of providing a generally circular climbing surface having a diameter on the order of eight to ten feet. 18. The method of claim 17, further comprising the steps of: allowing a second user to engage the climbing surface after the first user has disengaged from the surface; and adjusting the throttle to provide a resistance to rotation of the climbing surface until a desired rate of rotation of the climbing surface for the second user is achieved.
