What are the advantages of a treadmill over a stair climber?
assistant
The main advantage of using a treadmill versus a stair climber is that you can run at any speed and incline, whereas with a stair climber, you're limited to the set speeds and inclines. Additionally, running on a treadmill allows you to monitor your progress in real time, as opposed to stair climbing where you have no way of knowing how many steps you've completed until you get off the machine.
