Abstract: Data is managed by monitoring and generating data describing at least one first repetitive motion, such as a golf swing, executed by at least one individual at at least one first repetitive motion station located at at least one first location, and for monitoring and generating data describing at least one second repetitive motion executed by the at least one individual at at least one second repetitive motion station located at at least one second location geographically separated from the at least one first location. The data is transmitted from the first and second stations via a network to a network server computer having a data storage device, onto which the data is stored.
