Stairs that keep rotating give you no choice but to keep stepping, which is why the stepmill feels harder than an incline treadmill at a matched effort setting. Step rate is the whole intensity dial; rest the hands lightly on the rails rather than propping your bodyweight on them.
How to do the Stair Climber
- Adjust the stepmill machine to a comfortable level.
- Step onto the machine and place your hands on the handrails for support.
- Start walking by placing one foot on a step and then the other, alternating between legs.
- Maintain an upright posture and engage your core muscles.
- Continue walking for the desired duration or distance.
- Gradually increase the intensity or speed as you become more comfortable with the exercise.
- Remember to cool down and stretch after completing the exercise.
Tip: Swing the arms and keep an upright posture rather than leaning forward into the incline.
Muscles worked
Primary
Cardio · Cardio
Walking and elliptical work raise the heart rate at a moderate, easy to sustain level and are the simplest form of conditioning.
Secondary
- Quads
- Hamstrings
- Glutes — Incline walking and monster walks load the glutes with every step, especially the outer part of the hip.
- Calves — The calves push off on every step and get more work on an incline.
Common mistakes
- Holding the treadmill rails — leaning on the rails on an incline walk takes most of the work out of it; swing the arms and set the incline lower if needed.
- Slouching on the elliptical — keep the chest up and the shoulders back rather than leaning on the handles.
- Big, fast monster walk steps — keep the band tight, the knees bent and the steps short, since the whole point is constant tension.
- Strolling instead of walking — steady walking is easy, but that is the point; keep the pace brisk enough that you could talk but not sing.
Where it fits in a workout
Walking goes at the start of a session as a warm-up, at the end as a cool-down, or as its own easy conditioning on rest days. Monster walks pair well with hip abductions in a lower body warm-up.

When to talk to someone
- Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
- Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
- Pregnant: ask your obstetric care provider which exercise suits you.
