Abstract: Disclosed is a force measuring article of athletic equipment and method of monitoring caloric output during a physical exercise. Force transducers are positioned within the palm region of a lifting glove or sole portion of an athletic shoe for measuring force versus time data and storing the data for later retrieval and analysis.
