Well I've been on the treadmill alot lately. When I first got on in January, I could mantain 3.7mph while hanging on for dear life, lol. Now I can do 4.1mph while still holding on. My brother has told me that my left leg comes down a lot quieter now then when we first started going in Jan. so I think that is pretty positive. I'll admit though, I should pay more attention to HOW I'm walking, and not as much as how fast. For example, in order to make things easier, symetry is the key. I do think I still pick my left foot up slightly higher then my right like mentioned in the definition, now I guess that I need to try and relearn how to do it so well, like HeadCase mentioned, that I do it with out thinking about it, that's the goal. And as far as the 4.1mph goes on the treadmill, I'm not a tall guy by any means, so 4.1 was about my max walk even before surgery. So I guess the next step will be a slight jog. Hopefully that will come by the beginning of the summer.
