 Nashnyap, for cardio, would the Stairmaster be better than treadmill? Yeah, as far as I know, yes, because what I understand about the treadmill, when you're running a treadmill, the treadmill, when you put your foot down, you're running on a tread, and it gives you mini-vibrations, not even this, but mini-vibrations, and your body doesn't really like that over extended period of time. So when you, your foot hits the ground, you want to be solid. You don't want mini-vibrations. You don't want that, right? The other reason I believe the Stairmaster is better is because there's no impact, right? When you're running, there's impact. So you're working the ankles and the knee, they're getting that with the Stairmaster, you're not, right? That's my understanding of it. The bike is good.
