StepMill by Stairmaster
Sort of like a fast-moving escalator for the gym, this machine simulates climbing stairs – except the steps actually move! “This is one of the hardest pieces of cardio equipment,” says Westerman. “It’s like a treadmill with stairs.”
One reason it works so well for weight loss is the potential for calorie burn. You could climb the equivalent of 10 or 20 flights of stairs. “You’re working against gravity – essentially going up a flight of stairs – and you’re forced to bear most of your bodyweight,” explains Westerman.
“Plus,” adds Westerman, “you have to lift your foot off of the step and up onto the next step as opposed to a Stairmaster or elliptical trainer, where your feet stay planted on one step for the duration of the workout. This extra movement causes more work and burns more calories.”
