<human>: What are the benefits of a stair climber over a treadmill?
<bot>: The main benefit of using a stair climber over a treadmill is that you get more exercise in less time. A stair climber provides an aerobic workout with higher intensity, while a treadmill offers only low-intensity cardio. Additionally, stair climbing can help to strengthen your leg muscles and improve your balance. Stair climbing also has a lower impact on joints than running, which can reduce the risk of injury.
