Disclosed is a method for analyzing an athletic throwing motion by an individual. The method is executed by a motion monitoring system having at least one computer and at least one inertial sensor for sensing movement of the individual. The method involves the at least one computer receiving inertial sensor data from the at least one inertial sensor during execution of the athletic throwing motion by the individual, analyzing the athletic throwing motion by determining at least one metric from the inertial sensor data, and generating constructive feedback regarding the athletic throwing motion based on the at least one metric. The constructive feedback can for example be biofeedback and/or a prescription for a set of exercises. The constructive feedback can help the individual improve upon the athletic throwing motion. Also disclosed is a motion monitoring system.
