" Which indoor exercise machine is the best calorie burner? In two scientific studies, the treadmill won out over a stair climber, stationary bike, rowing machine, and cross-country ski machine. The reason? The male and female participants were able to exercise on the treadmill at a higher intensity without feeling fatigued, probably because walking comes more naturally than climbing stairs, pedaling, rowing, or skiing.  Still, this doesn&amp;#039;t mean that if you have a bike or stepper you should trade it in -- or let it gather dust. But instead of wearing yourself out at huff-and-puff speed, slow down a bit so you can exercise longer (at least 30 minutes) and get the same calorie burn-off. -- DELIA HAMMOCK, M.S., R.D., AND SAMANTHA BUCKANOFF, M.S., R.D.
