Abstract: A system for automatically providing high-intensity interval training (HIIT) is provided. The system may include exercise apparatus which a user manipulates to achieve exercise and which is controllable to provide an exercise profile having a high-intensity exercise interval to the user during user exercise. A stimulator subsystem is controllable to provide sets of stimuli to the user during user exercise including a set of stimuli capable of evoking a pupillary response in the user. An imaging assembly images a pupil of an eye of the user during user exercise to obtain a set of images of the pupil. An image processor processes the set of images to obtain measurements which measure the pupillary response. A system controller controls the exercise apparatus and the stimulator subsystem so that the exercise apparatus automatically provides the high-intensity exercise interval to the user based on the measurements.
