an exercise apparatus including a base , a platform , and a resilient member located between and attached to both the base and the platform . the resilient member can rotate , twist , and tilt in every angle while also providing a resistance force to all degrees of movement . the platform may be modified by the addition of an elastomeric material over its surface to provide additional traction or padding . the platform may also have notches placed around its perimeter , through which resistance tubing or rope may be placed such that upper body resistance motion may be integrated into the exercise apparatus . furthermore , support members may be disposed under both the platform and base for additional support and rigidity . the resilient member may have a flange , which in conjunction with an adjustment mechanism , may affect the amount of resiliency of the resilient member . the adjustment mechanism may have a handle , a gear and ratchet assembly , and a plurality of locking mechanisms . the adjustment mechanism may be simple and easy to use in that a single movement of the adjustment mechanism will simultaneously adjust the plurality of locking mechanisms and ultimately adjust the overall resiliency of the resilient member .
