Abstract: The present invention discloses an exercise system that allows tracking and monitoring of the exercise motion performed by end-users and enables insight into previously unavailable performance metrics. In a preferred embodiment of the instant invention, an exercise system comprising a barbell equipped with a system to determine the motion path of the barbell when lifted by an individual. The system for determining the motion path and the weight-load applied to the barbell comprises an array of sensors that collect information during the exercise movement, transmit that data to a collection system and processing system for analysis. The fusion of the plurality of sensors allows tracking and analysis of complex movements such as Olympic lifts (e.g., snatch or clean-and-jerk). For example, during exercise the motion and weight-load of the barbell of the instant invention is tracked and analyzed. The results of the analysis are reported to the athlete to improve the lifting form/technique or performance.
