|The Time Machine|
The treadmill functions like any other, but it automatically takes your weight, and then you can push a button to simulate 80%, or 65%, or 52% of your body weight! The giant bag fills with air and as you walk or run on the treadmill you become lighter! It is designed to take gravity pressure off injured knees, ankles, hips, spine, whatever. The machine is amazing -- of course it was designed by NASA.
So after getting used to the feel I upped the speed on the treadmill to 6.0, which is a quick jog, to 7.0, 8.0, 10.0 and now I was in a dead sprint and I felt like a Gazelle! My toes were bouncing off the treadmill with ease and I felt like a dog on a 4 hour car ride who is let loose in a large park. I was like Forrest Gump, I just could not stop running!
I was sprinting at 10.0 on the speed, and I was running at 65% of my body weight. I was now a freshman in High School running around with zero knee pain! It was exhilarating! I have not run that fast in literally decades and it felt so good (and exhausting!). After a while of running at full capacity I decreased the weight percentage back to 100% of my body weight. I was supposed to do this gradually, but the instructor was not around at the time.
