An exercise device for conditioning and rehabilitation of the nerves, muscles, bones, and joints of the body by facilitating or limiting range of motion and biomechanical forces around the horizontal and vertical axes. The device includes a fulcrum connected to a first side of a base. The fulcrum extends outward from the base and provides a point about which the device pivots. Fulcrum includes a recess having a removable attachment. When the attachment is connected, the fulcrum has a rounded shape. A user positioned on the base can pivot about the fulcrum in substantially 360째 of motion to fully work their body. When the attachment is removed, rails forming the recess limit the range of motion to a user to between substantially a first orientation and a second orientation. The range of motion with the attachment removed being less than the range of motion with the connected attachment.

What is claimed is: 1. An exercise device comprising: a platform; a fulcrum extending outward from the platform comprising a base with edges that define a recess, the edges defining at least two points of contact; and an attachment shaped to fit within the recess and having a rounded exterior surface complimentary to a semi-spherical exterior surface of the fulcrum; in a first orientation the attachment is removed from the recess and the device pivots on an underlying support surface about the edges of the base on the at least two points of contact and in a second orientation the attachment is positioned within the recess and the device pivots on the underlying support surface about a single point of contact formed by the rounded exterior surface of the attachment. 2. The device of claim 1, wherein the device further comprises a shoulder extending outward from the base and the attachment, the attachment being positioned within the recess such that the shoulder on the attachment aligns with the shoulder on the base. 3. The device of claim 1, wherein the recess is substantially rectangular in shape. 4. The device of claim 1, wherein the recess is substantially triangular in shape. 5. The device of claim 1, wherein the recess comprises straight interior walls with the edges that define the recess being pointed. 6. The device of claim 1, wherein the edges are substantially flat. 7. The device of claim 6, wherein the attachment comprises wings that mate with the edges when the attachment is positioned within the recess in the second orientation. 8. The device of claim 1, further comprising a locking mechanism for locking the attachment within the recess in the second orientation. 9. The device of claim 1, wherein the recess comprises main edges and secondary edges with the main edges contacting a support surface in the first orientation as the device pivots. 10. The device of claim 8, wherein the main edges are parallel. 11. The device of claim 9, wherein the main edges are oblique. 12. An exercise device comprising: a platform; a fulcrum attached to the platform, the fulcrum having a pair of rails separated by a recess with the rails extending below the platform; an attachment sized to be positioned within the recess and extend beyond the rails; the fulcrum being adjustable between a first orientation with the attachment removed from the recess and the rails contacting a support surface to provide at least two points of contact for movement to the base between a first and second direction approximately 180 degrees apart, and a second orientation having the attachment positioned within the recess with the attachment contacting the support surface to provide one point of contact for movement in substantially 360 degrees. 13. The device of claim 12, wherein the pair of rails are parallel. 14. The device of claim 12, wherein the rails have a pointed orientation. 15. The device of claim 12, wherein the rails have a flat orientation. 16. A method of using an exercise device on a supporting surface, the method comprising the steps of: pivoting the device in a first range of motion of about 360 degrees with a fulcrum and an attachment contacting the supporting surface; removing the attachment from the fulcrum member; and pivoting the device about rails that contact the supporting surface in a second range of motion that is less than the first range of motion. 17. The method of claim 16, wherein pivoting the device in the second range of motion comprises pivoting between a first direction and a second direction that are about 180 degrees apart. 18. The method of claim 16, further comprising limiting the range of motion by contacting a platform that supports the user against the supporting surface. 19. The method of claim 16, further comprising compressing the device towards the support surface when pivoting the device. 20. The method of claim 16, further comprising locking that attachment within the fulcrum member.
