Abstract: Method and apparatus for exercise in which a preselected work input to an exercise machine that is associated with an award-granting switch triggers a reward. The input can be a particular rate of work as measured by rotational speed or linear motion or a summation of the time during which a threshold level of work was exceeded. The reward can be turning on a TV or like electrical apparatus or it can be a change in the exercise machine and regime. An exercise machine incorporating the award-granting switch is disclosed in which the reward is a change in the angle to horizontal at which the exercise is performed. This change can make the exercise harder or easier depending on the exercise protocol desired.
