An exercise apparatus includes a support frame upon which is mounted a curvilinear track, the curvilinear track substantially conforming to a runner's footpath while striding. A first foot engaging support is secured to the curvilinear track for movement thereabout while exercising in accordance with the present invention. A resistance assembly is secured to the foot engaging support for applying resistance as a user moves the foot engaging support about the curvilinear track. A slide including a curvilinear carriage rides upon the curvilinear track and a first user engaging support is coupled to the slide for movement about the curvilinear track. A linear carriage rides upon a linear carriage rail supported by the support frame and a resistance assembly is coupled to the linear carriage. A slide bar links the curvilinear carriage of the slide to the linear carriage for the application of resistance as the user engaging support is moved about the curvilinear track.

The invention claimed is: 1. An exercise apparatus comprising:a support frame upon which is mounted a track, the track substantially conforming to a runner's footpath while striding;a first foot engaging support secured to the track for movement thereabout while exercising;a resistance assembly secured to the first foot engaging support for applying resistance as a user moves the first foot engaging support about the track; andwherein the shape of the track is approximately formed in accordance with the formulas x=L*cos(c)−M*cos(a−b) and y=L*sin(c)−M*sin(a−b), where c is thigh angle relative to a horizontal at a hip joint, a is knee angle, b is 2π−c, L is femur length, and M is tibia length plus shoe sole thickness.
