ATLANTA, May 2 (UPI) -- Only 20 percent of U.S. adults meet both the federal government's aerobic and muscle-strengthening physical activity recommendations, officials say.
However, the findings, published in the Morbidity and Mortality Weekly Report, a journal of the Centers for Disease Control and Prevention, also found nationwide nearly 50 percent of adults got the recommended amounts of aerobic activity and about 30 percent engaged in the recommended muscle-strengthening activity.
