I ramped up my glider exercise to three miles/65 minutes. I got a great workout, lower and upper body. My muscles were all hot, my arms, back and shoulders worked just as hard as my legs. I went harder and faster today and I had an overall faster pace. I got nice and sweaty and I feel great, now. I think that I hit a bit of an endorphin release, near the end of my workout, I felt almost euphoric and a part of me wanted to keep on going. But I decided to stop at three miles. I Need to let my body work up to longer, harder exercise. But I am not going to take it too slow. I would like to be up to five miles in less than a month.
And my hips and knees still don't hurt as much as they do when I walk. And this is a good thing. :D
