The winner of the Slimkicker giveaway is Sha-Sha!
Hmm.. a good challenge idea is to do 10 jumping jacks everytime you pass a doorway. People might give you some crazy looks in public though.
Sha-sha, expect an e-mail from me soon! And if I see a lady doing jumping jacks in the doorway of the grocery store, I'll introduce myself! Congratulations. :)
