Not sure if your daily steps add up to "enough" exercise? Follow the evidence. The U.S. Department of Health and Human Services comes out with Physical Activity Guidelines for Americans every 10 years. That means an independent, scientific panel putting together the hard evidence on exercise and our health.

The guidelines explain why and how people can feel better with regular movement—people of every age, physical ability and health status. And spoiler alert: You don't have to hit the gym for an hour every day to reap the benefits.
