CDC Reveals America's Laziest and Most Active States The agency based its analysis on phone interviews conducted across the U.S. The data was compiled between 2015 and 2018. Outside of their normal job, people were asked if they had exercised or done any physical activity in the past month. According to the study, seven states had the highest rate of inactivity at 30 percent. The seven states were Louisiana, Mississippi, Alabama, Oklahoma, Arkansas, Tennessee and Kentucky. So which states are the most active? Utah, Washington, Colorado, Oregon and District of Columbia claimed the title. In these areas, the study says less than 20 percent reported inactivity from the phone survey. How much physical activity does one need? On a weekly basis, the CDC says you should reach about 150 minutes.
