The majority of U.S. adults aren't getting enough exercise.
The government's fitness guidelines recommend that every week people ages 18 to 64 should do "muscle-strengthening" exercises twice, as well as 150 minutes of moderate aerobic activity.
But data released Thursday by the Centers for Disease Control and Prevention estimates only about 23 percent of U.S. adults are working out this much.
The CDC based its estimates on answers provided to the 2010-2015 National Health Interview Survey.
The report broke down the data by state — Mississippi had the lowest percentage of adults meeting guidelines with just 13.5 percent, while Colorado had the highest number with more than 32 percent.
One of the report's authors told CNN that most of the states where adults were really working up a sweat and meeting guidelines were areas with colder climates, such as Massachusetts, Vermont and Minnesota.
Although 23 percent might seem low, it is a slight increase from 2013, when the CDC reported only about 20 percent of adults were exercising enough.
