A ski for use on ice or snow comprising: a ski body comprising a tip portion, a tail portion, and a longitudinal running length extending between the tip portion and the tail portion and a flat bottom surface for sliding on snow or ice; a suspension system comprised of a rigid support structure attached to the longitudinally central region of the ski body at two attachment locations separated by a distance of at least 12.7 cm (5 inches) along the longitudinal axis of the ski body, wherein one of the attachment locations is attached forward and one aft of a central longitudinal region of the ski body that exhibits a low flexural modulus relative to the flexural modulus of the ski body where said attachment locations are attached; and at least one central resilient element configured to exert an opposing force between the support structure and the ski body in the area between the two attachment locations, wherein expansion of the central resilient element that is configured to exert an opposing force between the support structure and the ski body between the two attachment locations causes the tip and/or tail of the ski body to bend upward, decreasing camber and increasing rocker, wherein compression of the central resilient element that is configured to exert an opposing force between the support structure and the ski body between the two attachment locations causes the tip and/or tail of the ski body to bend downward, increasing camber and reducing rocker; and one or more compressible elements positioned between the support structure and the ski body either forward of or behind the two attachment locations, where the one or more compressible elements are configured so that further upward deflection of the ski body beyond a predetermined degree of deflection will cause the spring rate of the ski body to be greater than that exhibited prior to being deflected to the predetermined degree of deflection. a ski body comprising a tip portion, a tail portion, and a longitudinal running length extending between the tip portion and the tail portion and a flat bottom surface for sliding on snow or ice; a suspension system comprised of a rigid support structure attached to the longitudinally central region of the ski body at two attachment locations separated by a distance of at least 12.7 cm (5 inches) along the longitudinal axis of the ski body, wherein one of the attachment locations is attached forward and one aft of a central longitudinal region of the ski body that exhibits a low flexural modulus relative to the flexural modulus of the ski body where said attachment locations are attached; and at least one central resilient element configured to exert an opposing force between the support structure and the ski body in the area between the two attachment locations, wherein expansion of the central resilient element that is configured to exert an opposing force between the support structure and the ski body between the two attachment locations causes the tip and/or tail of the ski body to bend upward, decreasing camber and increasing rocker, wherein compression of the central resilient element that is configured to exert an opposing force between the support structure and the ski body between the two attachment locations causes the tip and/or tail of the ski body to bend downward, increasing camber and reducing rocker; and wherein expansion of the central resilient element that is configured to exert an opposing force between the support structure and the ski body between the two attachment locations causes the tip and/or tail of the ski body to bend upward, decreasing camber and increasing rocker, wherein compression of the central resilient element that is configured to exert an opposing force between the support structure and the ski body between the two attachment locations causes the tip and/or tail of the ski body to bend downward, increasing camber and reducing rocker; and one or more compressible elements positioned between the support structure and the ski body either forward of or behind the two attachment locations, where the one or more compressible elements are configured so that further upward deflection of the ski body beyond a predetermined degree of deflection will cause the spring rate of the ski body to be greater than that exhibited prior to being deflected to the predetermined degree of deflection.
