According to USA Today, less than a third of Americans, and only one in five teenagers, meet new physical fitness guidelines issued by the federal government.

The guidelines recommend the same level of exercise as the standards released in 2008, but without the expectation that the physical activity occur in 10-minute blocks.

They call on adults to get at least 150 minutes of moderate-intensity aerobic physical activity and two sessions of muscle-strengthening activity each week.

Children ages 6 through 17 should get at least 60 minutes of moderate-intensity aerobic physical activity per day and three sessions of muscle-strengthening per week.

Muscle-strengthening activity includes lifting weights, heavy gardening, and yoga.  Please click on the above link for more information.
