A method and apparatus for pacing human exercises includes a sequence of pre-recorded, repetitive humanly perceptible signals in which a first, accented signal pulse, such as the first beat in a four-four measure of musical time, establishes a repetitive rhythmic tempo to thus provide timing track signal for synchronizing various phases of an exercise. The rhythmic pulses, which are preferably provided by a percussion instrument such as a drum and accompanied by musical tones, are accompanied by instructions verbalized by an exercise trainer in synchronization with the timing track signal. The perceptible signals are preferably audible and are optionally accompanied by or replaced by visibly perceptible signals such as flashing lights.
