Motivation Ideas...

the kids and I started a new thing ..we are each going to pay $2.00 every 2 weeks to a jar...and on weigh in days who ever gains will have to pay $1.00 per pound gained...we are doing this "biggest loser" for 5 months who ever loses the biggest % of body fat will win all the money in the jar!!{my kids are 19 and 12,both need to lose weight,my 12 yr old son actually has lost alot already,but docs said he still needs to lose another 40lbs....he is 5'6 tall and doesn't look over weight his pic in in my profile!
