Strength training is becoming increasingly popular among all age groups, as it helps participants increase muscle strength, improve body flexibility, reduce health risks and reshape physical forms. However, strength training imposes strict regulations on gestures and requires professional instruction in real time for the sake of body-building efficiency and safety. For this purpose, in this paper, we propose a novel low-cost system named iCoach, to provide real-time monitoring and coaching service for strength training participants. Specifically, we design and implement a smart fitness glove, which can be seamlessly equipped with a pervasive inertial unit. With this customized but low-cost device, we can recognize various training programs, detect non-standard behaviors while exercising, and assess exercising qualities of a user. Our primary experimental results show that iCoach can recognize fifteen sets of training programs, detect three common non-standard behaviors and assess the quality of training with high accuracy and reliability.
