We started this a long time ago but if you are physically active for at least 30 minutes 5x a week for 6 weeks you get a cool certificate.
We actually have a club started called the 100lb. clubbers but I don't remember who started it to get the code for you. I tried to doing a search and came up with nothing.
I've started entering my info on there again and that is one of my goals is to get the cool certificate.
