$20 to start the competition...Goal is to lose 1% of body weight each week or else you must pay $5 dollars. At the end (Friday - April 16th (15 weeks)) if you've meet the minimum body weight loss (15%) then we split the money within the pot. Therefore, you're not out a dime if you're able to meet your weight at the end. (Note: minimum weight loss is 15%, however you may lose as much weight as you desire just remember you have to use 1% of your weight loss weekly or you must pay $5.) Let me know if you have any questions! Good luck!
