Any activity that uses large muscle groups, can be maintained continuously, and is rhythmical
in nature can be regarded as an aerobic exercise. In general, aerobic exercises requiring little
skill to perform are more commonly recommended for all adults to improve fitness. Aerobic
exercises that require minimal skills and can be easily modified to accommodate individual
physical fitness levels include brisk walking, leisure cycling, swimming, aqua-aerobics and
slow dancing. Aerobic exercises that are typically performed at a higher intensity and,
therefore, are recommended for persons who exercise regularly include jogging, running,
aerobics, stepping exercise, fast dancing and elliptical exercise.
