The late 1960s brought a revolution in exercise. The Aerobics movement captured the attention of everyone and created an exercise boom that has endured. However, it became apparent that far too many adults were not engaging in exercise according to the recommended duration, frequency and intensity. For many, these guidelines were just too restrictive. A burning question emerged: does one really have to exercise according to this longstanding "exercise prescription" or are lower amounts of exercise also beneficial?

One of the most profound developments of the 1990s has been the publishing of the first ever Surgeon General's Report on Physical Activity and Health. This report made it clear that lower amounts of exercise and activity could have significant health benefits. This module will discuss the newer recommendations for both health-related and fitness-related activity.
