Low levels of physical activity and fitness are associated with a 2-fold
increase in risk of all-cause and cardiovascular mortality.1,2
The cardiovascular and mortality risk associated with low physical fitness
is similar to, and in some cases higher than, the risk attributable to diabetes
mellitus, high cholesterol levels, hypertension, or cigarette smoking.3 Yet only 15% of adults engage in regular vigorous
physical activity, and 60% report no regular or sustained leisure time activity.4
