Despite the many benefits of physical activity, initiation and maintenance
rates in the general population are disappointing.1 The
majority of US adults are either completely inactive or do not meet the recommended
guidelines of 30 minutes of moderate activity 5 times per week or at least
20 minutes of vigorous activity 3 times per week.2 Recent
estimates from the Centers for Disease Control and Prevention (CDC) Behavioral
Risk Factor Surveillance Survey1 suggest that
27.6% of adults perform no activity, 46.2% perform some activity, and 26.2%
meet recommendations.
