Abstract: A method and system for training the movement of a golf club that includes a mobile device that receives positional data based on movement of a golf club and stores summation parameters of golf club movements in a trainee database. In addition, the mobile device builds a training envelope that determines the parameters for training and detraining movements. The mobile device then selects a best movement from a plurality of training iterations and outputs an instantaneous feedback based on the positional data during the training iterations. The best movement is the positional and rotational data generated by a best swing. A new best movement is determined from a training iteration that produces a better result than the previous movement.
