Slim down while adding precious minutes to your day
Stairs or elevator? To save time and boost fitness, climb rather than ride--it shaves off 20 seconds per flight, report University of South Carolina at Aiken researchers who clocked office workers traveling from floor to floor. Plus, stair-climbing burns 100 calories every 11 minutes--as many as jogging--while toning hamstrings, quads, and glutes (the muscles of the hips and thighs), making it one of the best butt firmers around. Not bad for a workday workout.
