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.
