New challenge ideas?

Hi everyone, I think we're all maybe getting a little bored of the challenges, I know I am bored of the Wii one slightly but am still going to do it.
I feel we need a new kind of motivation and would appreciate your ideas of what you'd like to do - I was thinking an EA Sports Active Challenge maybe?

Or if everyone would like we could do just an Exercise Challenge and welcome all forms of exercise? I really don't know but I'd like some new ideas and I like having the motivation of a challenge thread so chuck your ideas in the ring folks

ooo im new on here so never done one of these before? sounds good! i havnt got a wii tho i sold it and ive got 2 young children - what sort of challenges have you done before?x
