An exercising machine is disclosed which can move in any direction in the X-Y plane on a multi-directional track. The head engaging member is coupled the multi-directional track and the multidirectional track is coupled to an arm that is moveable up and down on a frame to accommodate users of different heights. In one embodiment the multidirectional track is a swivel-able on the arm and as a user pushes the head engaging apparatus in a direction, the track will align with the direction of the user's push and then the rollers will start rolling on the track. In another embodiment the multi-directional track includes a first track mounted to a second track and the second track is mounted to the head engaging harness, wherein the first track can move in a first direction and the second track can moves in a second direction allowing the head engaging member to move in an infinite amount of directions in the X-Y plane. In another embodiment, as an exerciser moves the head engaging member in the X-Y plane the machine forces movement in the Z plane such that the head engaging member can maintain a point of contact on the users head as the exerciser rotates his head during exercise. At least one biasing member is coupled between the frame and the head engaging member to place a biasing force on the head engaging member. As a net force is applied to the head engaging member by the user, the biasing member(s) resist movement from the rest position thereby providing resistance to the user as the user exercises the muscles of the spine. The track can be arced or formed in a radius such that the head engaging member traverses a motion approximate to a radius of a neck rotation as measured from the forehead to the base of the neck. In other embodiments push rods roll on a dish surface to provide the arc movement of the head engaging member. In other embodiments, the arc of travel of the head engaging member can be adjusted by the user to accommodate the dimensions of the user.
