How Many Calories Does the StairMaster Burn?

StairMaster consoles lie cheerfully. Lean on the rails and your real MET collapses while the screen stays heroic.

Working MET ≈ 9 (vigorous stair-climber machine). At 70 kg that is ~315 kcal / 30 min. Scale for bodyweight; long rests lower the real total.
