A retrofittable exercise data collection system and method of collection of data concerning the performance of weightlifters and the like which can be attached to a power rack used by weightlifters and detached after use or alternatively set up in freestanding arrangement in which by emitted electromagnetic radiation coupled detectors the movement of a barbell past such emitters may be detected and the speed of passage calculated by determining the interval between occlusion of the detector beams between adjacent detectors, the height of such occluded detectors being related to the portion of the musculature of the weightlifter that is undergoing extension or retraction during exercise.

I claim: 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. 2. A method in accordance with claim 1 wherein the channels are provided with magnets which when the system components are moved to an exercise site are brought into contact with the metal structure of the power rack such that the channel members are secured to the end posts of the power rack. 3. A method in accordance with claim 1 wherein the data is stored in memory of the system for further reference. 4. A method in accordance with claim 3 wherein the channels are provided with magnets which when the system components are moved to an exercise site are brought into contact with the metal structure of the power rack such that the channel members are secured to the end posts of the power rack.
