ABSTRACT:
An exercise apparatus for assisting a person to safely do free weight lifting exercises without the aid of a human assistant. The apparatus is comprised of a pair of vertical cables secured at their upper ends to an overhead support structure, such structure dependent on the physical environment at the apparatus location, e.g. ceiling beams and trusses, weightlifting frames. The lower ends of the cables are not secured. A pair of clamp assemblies telescope over the cables and the weight bar is secured to the clamp assemblies. A control bar, parallel, above and proximate to the weight bar, connects to clamp assemblies. The control bar causes the clamp assemblies to grip and release the cables. When doing an exercise, the user squeezes the control bar towards the weight bar to release the cables. To terminate the exercise the user releases the control bar which in turn causes the clamp assemblies to grip the cables and therefore support the weight bar. When an exercise is in progress the cables move freely through the clamp assemblies and therefore do not exert any forces on the weight bar, and do not constrain the movement of the weight bar in any axis. Therefore exercises done with this apparatus are true free weight exercises.
