Each week or month depending on how you want to do it, they come to get weighed in.
Each week the group gets an email from challenge lead with different challenges, motivational quotes, try something new, etc.
Staff pay $10 to join and if they miss a week or go up in weight they pay $1 to the pot. You can modify this as you see fit. Some challenges charge more for sign up but do not charge for missing a week or weight gain.
At the end of the challenge, participants weigh in and get measured.
The top three overall percentage of weight and inch loss win the money pot.
