magic that other cardio equipment can’t quite match. Compared with the usual suspects (rowers, Spin bikes, ellipticals, stair climbers, cross-country ski machines), treadmills can help you burn more calories at every intensity. “Also, running on a treadmill promotes dynamic balance, something you don’t get on seated equipment like a bike or a rower,” says Christi Brewer, Ph.D., an assistant professor of exercise science at Eastern Washington University. A new study by Brewer showed that a treadmill run can even outburn a high-intensity weight circuit. At the same heart rate, exercisers doing a steady 20minute treadmill run burned 37 percent more calories (206) than doing
20 minutes of circuit training with weights (fast-paced reps for 30 seconds and no rest between sets), even though they rated circuits much higher in perceived exertion. “While circuit training does get your heart rate within an aerobic training zone and feels more strenuous than treadmill running, it does not burn as many calories at the same heart rate,” Brewer says.
