Americans spend nearly five hours a day -- an average of 151 hours a month -- parked in front of the TV, repots Nielson Media Research. While there's nothing wrong with catching up with What Not to Wear (in fact, we encourage it!), channel surfing is no substitute for exercise. We all should trade button pushing for bench pressing. Or at least take a walk around the block.
According to the Center for Disease Control (CDC), adults should aim for a minimum of 30 minutes of moderate exercise a day, enough to break a sweat, five times a week. There's no need to do it all at once or even join a gym to hit this goal. If you use a spare 10 minutes to walk around the block three times a day, five days a week you'll hit that 150 minute recommendation.
And yes, mowing the lawn for 10 minutes counts!
