A static dynamic exercise apparatus is provided. A spatially displaceable object is coupled to a frame and coupled to a force applicator. A resistance system exerts a first level of resistance that prevents the movement of the object by the application of a user-applied force, thereby allowing a user to generate a static, or isometric, force on the force applicator and object. The resistance system may then be released, to allow movement of the object, thereby rapidly transmuting the static force into a dynamic movement. In various embodiments, the object is a plurality of weights, the force applicator is a weight lifting bar, and the resistance system is a pneumatically actuated piston that is capable of releasably holding the weights and weight bar to the frame. |
