Americans flunking fitness: Survey reveals lack of basic diet and exercise knowledge [Infographic]

(BPT) - Americans talk a good health and fitness game, but flunk when it comes to their actual knowledge. A new survey from Nautilus, Inc. found Americans are failing in basic fitness, health and nutrition smarts.

In fact, respondents scored 42 percent overall. If this survey were a class test, they'd have earned an F grade.

No matter what an individual's health and fitness goals may be, understanding the fundamentals should be simple.

The Nautilus survey, powered by Instantly Survey Tool, questioned 1,038 men and women in the United States ages 18 and older in April 2015 to gauge Americans' acumen when it comes to nutrition, health and fitness.
