Abstract: Green light therapy includes the showing of results of training in real time. This has been shown to increase the overall output and efficacy of the training regimen using the equipment. A sensor and programming are used with different training equipment for training, rehabilitation, or muscle building exercises for use with neuromuscular disorders to provide the real time feedback to the user of the equipment. The feedback will aid in obtaining the desired output by the user and to attempt to maintain the desired output throughout the training session. Thus, the feedback can help improve the results of the training for user.
