Kinect achievments!

I don't own a Kinect myself (yet!) but these achievements look a bit challenging! Keeping fit and getting achievements, sounds amazing to me. I mean come on, look at these from EA Sports Active 2:

Golden Gloves    25G
Throw 1000 punches in Cardio Boxing

Pumping Iron      20G
Perform 1000G arm curls

These kind of achievements will have the majority of us looking like Marcus Pheonix. A godsend for the slightly over weight Gamerscore addicts! Anyways, this looks like it's floating my boat completely, can't wait to get it bought and get stuck in!
