It’s no secret that sitting all day damages your body, but figuring out a system to counteract that for yourself is tough. The New York Times suggests one simple rule you can employ is a variation on the 20-20-20 rule to reduce eyestrain, but with movement instead.
The idea here is pretty simple. The best way to counteract the negative effects of sitting is to get up and move. The 20-20-20 rule just makes that easy to remember:
Jack Dennerlein, a professor at Northeastern’s Bouvé College of Health Sciences in Boston who specializes in ergonomics and safety, suggests a variation on the 20-20-20 rule used to reduce eyestrain.

But Dr. Dennerlein notes that this eye rule can be applied to movement as well. Every 20 minutes, walk 20 feet away for 20 seconds or more. Stop by a co-worker’s desk. Get a cup of coffee. Pace.
