US Patent 8721509 Tiltable multi-purpose variable resistance exercise gym apparatus

A table is slidably supported on a chassis which is tiltably supported on a base or support frame whose angle may be adjustable via a motorized tilt control device that allows the chassis and table to be tilted and the weight of the user made available to produce a load against which exercising can be carried out. Said weight may be increased by the addition of one or more elastic resistance bands at various geometric points of said slidable supported device and the fixed base on which it is mounted, and whose geometry serves to apply a pre-tension force to said band(s). By pre-tensioning the material, the resistance band then provides a more linear force to the end user.
