Treadmill 1 Me 0 in hi

So, I am having knee replacements in January. Yes, both, because why wouldn’t I think that was a great idea. Being that it is in January walking outside will be hard, so my son lent me a treadmill he isn’t using.
Let’s preface this with I HATE to walk, it’s so inefficient . Takes forever to get somewhere, but, I really owe it to myself to use the treadmill before surgery.
So yesterday I try it. Music, on, I was doing great , trucking along for 5 whole minutes before I was bored out of my mind. I get off and grab a book..Good times, I can read and walk along. I was going a nice 5mph clip, reading away. Life was great until I needed to turn the page. I rested the book on the TOUCH screen to turn the page. Right on the spot where the “programs” are. Apparently I hit a button that set the treadmill to 10mph.
I cannot run 10mph. Let’s just say it wasn’t pretty or graceful. I have bruises and scrapes all over my body. The GREAT news is that my face hit the book so it is unscathed .
Lesson: exercise is the devil
