Curious, I would love the link. Like Cherie I have no idea.....

Sorry, Cindy

Cherie, my legs are weak and it's the stiffness that keeps me up and moving. I like the treadmill and have been known to swear at my legs as I'm on it

My max on the treadmill is 2 miles. I haven't been able to get to my max in quite awhile. I have now increased the incline to 3 percent, at 3/4 of a mile with a max speed of 2.1 - I'm short so my speed is limited otherwise I'm running and that's NOT going to happen
