"Biggest loser" type challenge question...
My family is wanting to all pitch in some money each month and have a winner every month for weight loss and getting healthy type challenge. I'm trying to put together a challenge group for us but we are all at such a wide range of weight loss goals so I'm trying to come up with a better way to pick a winner each month. I was thinking bf% but I wanted to ask here to see if anyone had any better ideas?
