The highest proportion of adults meeting those guidelines were in the West (24 percent) and the Northeast (21 percent).
Women, Hispanics and older and obese adults were less likely to meet the guidelines, they added.
"Exercise is essential for the aging population to maintain their independence and quality of life," Heller said. "The results of this report indicate that certain states and populations need to be targeted with programs that encourage regular physical activity while taking into account their cultural and economic needs. Local YMCAs, senior centers and other organizations often offer low-cost or free fitness classes."
"Simple steps to start moving include: enlisting a friend or family member to join you; taking a walk every evening after dinner; getting up and marching in place at every TV commercial; limiting TV and computer time; [and] scheduling your time to exercise in your daily calendar," Heller said.
These data are based on information from the Behavioral Risk Factor Surveillance System, which is a yearly phone survey of adults aged 18 and over.
