DYK: How Much Exercise?

I’m always pressed by people who want to know what they need to do for the bare minimum of fitness. Of course, many ask how to train for marathons. But there is always someone who says “do I have to do ALL that?”

So here it is…

According to the Center for Disease Control (CDC), adults need a minimum of 150 minutes of moderate-intensity aerobic activity a week in order to improve overall health and fitness and reduce risk for many chronic diseases. Moderate-intensity exercise is defined by activities as simple as brisk walking.

Before you launch into “OMG 150 MINUTES!! THAT’S CRAZY!!” do the math. That comes out to 21 minutes and 25 seconds a day. So for 22 minutes every day, you need to walk briskly in order to improve your overall health.
