I'm a 57 year old teacher who just had total knee replacement last November 07. I'd like to loose 10, actually 9.5 now! to get ready for bicycling season but also to keep extra strain off this new knee so it lasts longer than predicted 15-20 years. My husband and I tandem ride and he likes to keep total weight on the bike down so we can go faster. He's the main cook and very supportive.He also serves as my coach and trainer. I plan the menus and he executes. Here's to ten pounds by spring break.
