Weight loss Challenge

So My dad, Husband and two friends Dave and Jerry, and myself are all doing a weight loss challenge :) It goes for 90 days and the most percentage lost is the winner of $500...woohoo...i have been working hard and already lost 4 lbs since sunday morning :) Thats over a pound a day. I am going to blog my success cause it helps keep me motivated. I am going to be on a strict diet and doing ChaLEAN EXTREME..She is amazing! I will be using ISAGENIX. I will also be biking everyday and trying to run..not sure the runnin will work cause i have a horrible back :) lol...wish me luck
