How about running on the treadmill.

The numbness in my feet doesn’t give me enough feedback so I can run in a straight line. I keep drifting off to the sides. Maybe I should just go ahead and set up a video camera and go for it. It might be a funny home video moment. 😀

I also don’t tend to walk in a straight line (treadmill or not). I get off balance to one side or the other. I tend to run into the walls when I turn corners.

umm i use a treadmill a few times a week but for building endurance try a stationary bike maybe from a garage sale u can get one really cheap and if you get tired you just slow down and no chances of having accidents. hope that helps
