7. Climb 3 extra flights
Have a choice between riding and climbing? Including 2 to 3 minutes of stair climbing per day—covering about three to five floors—can burn enough calories to eliminate the average American’s annual weight gain of 1 to 2 pounds a year. It’s also good for more than just your waistline: Men who climbed more than 70 flights of stairs a week had 18% lower mortality rates than those who climbed fewer than 20 flights a week, according to one Harvard study. Start with just a couple of flights a day; if you’re already a dedicated climber, aim to add three more flights to your daily trek.
