1 he American Heart Association recognizes the lack of aerobic exercise as being a “contributing factor to the presence of coronary heart disease.”
It recommends participation in aerobic activity (i.e. jogging, swimming, brisk walking, vigorous dancing) at least three days a week for 15-60 minutes to produce cardiovascular fitness.
