I'm thinking about getting a under the desk pedal exerciser. G, my co-worker, said it sounded gimmicky to her, but I can really see myself using it. Working 10-15 hours per day has me just about ready to jump out of my skin and I think being able to pedal away while I sit here reviewing documents would a) make me feel better about sitting on my bum all day, and b) stave off the crazy nervous energy jiggles.
Has anyone used one of these? What did you think?
