An exercise training system is provided having a system controller and a plurality of stimulant target units connected via a wireless network to the system controller. Each stimulant target unit has a light source providing light to stimulate a user, a proximity sensor providing an output of a distance between the proximity sensor and an object external to the unit, and means for providing feedback to the user to signal that the unit has been actuated by the user. The system controller includes a program for activating the stimulant target units in a sequence. The reaction by the user to the illumination is registered when the user brings a body part or other object to within a selected distance of the proximity sensor, this distance being programmable by the user.
