A workout system for monitoring fitness and generating a workout summary is disclosed. The system includes a workout module that integrates with weight lifting equipment. The workout module includes one or more motion detectors that detect repetitions and/or tempo of weights lifted or displaced and a computer that logs and stores the repetitions and/or the tempo that weights are lifted or are displaced. The workout module also preferably includes a resistance, a radio frequency, an optical or a magnetic weight sensor or reader that automatically reads and determines values of weights used in the workout. The workout module also preferably includes a radio transmitter to transmit workout data and workout parameters to a remote computing device.
