Abstract
A Mobil Variable Hydraulic Resistance Exerciser which allows a user to be in motion throughout the complete exercise movement. This exercises the muscles of the feet, ankles, knees, hips, spine, legs and trunk of the body by providing a constant resistance to the user while in motion. A variable hydraulic reservoir is used to regulate the amount of resistance applied thru the Mobil Exerciser.
Claims4
An exercise device comprising:
- a sled mounted on an elongated substantially linear track for movement thereon;
- a substantially horizontal elongated arm mounted on said sled perpendicular to said track for transmitting force applied to the arm by the user to the sled to cause the sled to move along the track;
- and
- a variable hydraulic resistance mechanism for resisting movement of said sled along said track, said variable hydraulic resistance mechanism comprising an hydraulic reservoir and a pair of opposing hydraulic pistons operatively connected to said reservoir via a pressure line for applying a resistance force to said track.
