Ha ha! Improvised Nordic Trek by skating in sox on a hardwood floor?
You can get the real thing
, used, for $50 over in Kirkwood. It' s a good warm-up to more serious exercise. Kinda like an elliptical machine that doesn't have to be plugged in. And it's been 10 years since Soupbone gave me his, and absolutely no maintenance has been required...which you can't say for a treadmill!
