ABSTRACT:
A safety apparatus for use with a barbell assembly includes a support frame, a pair of cables which are securable to opposite ends of the barbell assembly, a winch assembly on the support frame for retracting and releasing the cables, a pair of tension sensors for sensing the tension in the cables, a velocity sensor for sensing the speed and direction of movement of at least one of the cables and a controller for controlling the operation of the winch assembly. The controller is responsive to the tension sensors and the velocity sensor for normally releasing and retracting the cables during a weight lifting routine so that the safety apparatus is normally unnoticeable to a weightlifter. The controller is also responsive to the sensors for detecting an abnormal condition during an exercise routine and it is operative in responsive to an abnormal condition for taking control of the barbell assembly to reduce the risk of injury to the weightlifter.
