Don’t Just Sit There, Work Out at Your Desk

EVERY day, millions of American workers do something dangerous to their health: they sit down.

Sitting for long periods is hard on the body. It strains the back and causes the muscles to become slack. It slows the processes that metabolize calories, increasing the risk of obesitydiabetes, heart disease and some cancers.

People might think they are protecting themselves from such problems if they exercise outside of working hours. And employers may pat themselves on the back if they offer their workers subsidized gym memberships. But regular exercise doesn’t entirely make up for the shutdown of chemical processes that occurs during long periods of sitting, research has shown.
