1. A method of providing weightlifting data to aid competitive weightlifters increase their performance by means of an electronic movement detector system comprised of a series of spaced electromagnetic wave detector couple members housed in opposed channel members having in one channel a series of electromagnetic wave emitters and in the other channel a series of electromagnetic wave detectors, the two series of detectors being coordinated with each other and electronically connected to an electronic computer and display means, the opposed channels having associated therewith means for removable attachment in opposed relationship to the corner posts of a power rack comprising:

  • (a) moving the system components to an exercise site and securing the electromagnetic detector couple members to the corner posts of a power rack;

    (b) aligning the detector couple means so the electromagnetic emitters and detectors are correctly aligned to determine which emitters are operating at a given time;

    (c) operating the detector couples in conjunction with the electronic computer and the electronic computer components while a weightlifter is lifting weights within the confines of the power rack with a portion of the weight equipment extending through the detection beams;

    (d) calculating the rapidity of movements of various portions of the weightlifters body based upon data provided by the occlusion of the electromagnetic emitter emissions as indicated by the detectors by the extension of the weight apparatus as the weightlifter performs and by reference to the height and rapidity of the occlusions of the beams determining the rapidity of response of anatomical portions of the weightlifters body;

    (e) displaying the results of such calculations on the electronic display means.
