A training device for a person performing a physical activity wherein the proper performance thereof is related to the proper movement by the person. The device comprises a movement sensor, a trigger event sensor for sensing the occurrence of a specific physical trigger event, a processor, an electronic memory, and a protective enclosure. The movement sensor provides movement signal values to the processor, which is able to store these movement signal values in the memory. The trigger event sensor provides trigger event signal values to the processor, such trigger event signal values corresponding to the occurrence of the specific physical trigger event near the device. The processor is able to store the trigger event signal values in the memory and evaluate the trigger event signal values to determine if the specific trigger event has occurred. Upon detection of the trigger event, if the movement signal values are not within a first pre-defined range, the processor takes a first notification action. Otherwise, the processor takes a second notification action. A notification transducer is included for signaling the notification actions of the processor to the person, who is thereby notified of the correctness of his performance of the physical activity relative to the occurrence of the particular trigger event. The processor may also evaluate other characteristics of the trigger event signal values to determine the correctness of the performance of the physical activity.
