Here are the rules:
The fastest to shed 2% of body weight wins.
To calculate 2%, just multiply .02 with your body weight and round off to the nearest 0.1/0.2/etc. lbs. (whatever your scale shows). Winner starts the new thread!
If you go to the Chicks up for a Challenge forum, up at the top left there will be a button that says "New Thread". Then it is pretty much like making a post.
