1) What does a Stair Stepper do for your body? The Stair Stepper is an effective way to strengthen and tone your legs, thighs, and butt, according to Tom Holland, MS, CSCS, and author of Beat the Gym. With each step, you're lifting your body weight and activating the major muscle groups in your lower body—including your glutes, quadriceps, hamstrings, and calves.

An average treadmill workout can burn up to 700 calories if you run at a high intensity. A similar intensity Stair Stepper workout will burn closer to 400 calories. However, if you run or walk at a lower intensity, the Stair Master is an excellent alternative since it combines cardio and resistance training. 3) Can you lose weight doing the Stair Stepper Machine? The Stair Stepper is an efficient and effective tool in losing weight or managing your current weight. A half-hour workout on the Stair Master can burn anywhere from 180 to 260 calories — or more — depending on your body weight and intensity of the workout. A faster “climb” will burn more calories than a slower session.
