When it's too cold for cycling, I go to the Y.M.C.A. I usually start with some time on the LifeCycle--they have a few uprights and many recumbents, both kinds the most uncomfortable machines I've ever planted my keester on, but that's a different issue. As long as I've been going to gyms I've noticed that a lot of people climb on the exercycles and cover the displays with their towels. What's up with this? Are they, in some kind of reverse vanity, hiding that they have the things set a a level they consider embarassingly low, or does covering the display somehow help them with their workout?
