Sorry about that. I'm new at this computer forum thing. I keep assuming that everyone on here is in my State. Gold's gum is a giant chain of work out gym's. I believe they're all over the U.S. There are alot here in California. Plenty of exercise bikes. I will go in tomorrow and do what you suggested. Thank's for the info.sogood said:No idea what's "Gold's gym". In any case, get on any exercise bike and play around with the power setting and see what kind of power you can maintain for an hour at a stretch. May not be super accurate but it'll get you into the ball park. If you are going off the scale, then you may well be in for a chance.
