The place where I go to PT just got a new treadmill, the Alter-G Anti-Gravity treadmill. My PT was telling me all about it at my last session. I saw the treadmill at the ACSM conference a few years ago. It sounded amazing. It applies a lifting force (air) to the body that reduces weight on the lower extremities.
After my PT session today, my PT asked if I wanted to use the treadmill for my run. Of course, I jumped at the chance to use it. I loved it.
You start out by putting on a pair of neoprene shorts (over your shorts) that zip into the treadmill to form a seal. The treadmill weighs and fill up with air. Then you select what percent of your weight in which you want to run and increase the speed. You are off and flying. I mean flying and not working as hard as you normally work. Imagine being able to run at only 50% of your body weight. You can run so much faster.
The Alter-G websites says "Run or walk like you are on the moon." Well, I love the idea of less gravity but the lack of oxygen on the moon would make it so much harder. :) So running on the moon for me is a toss up, less gravity, less oxygen. I think I will stick to this treadmill.
I will jump at the chance to run on this treadmill again.
