My newest ENEMY (er, I mean friend)

Here's the newest piece of equipment at the YMCA that has been my enemy/friend...or I guess I should say "Frienemy".  I had seen it and had been wanting to try it, instead of the typical elliptical/stepping machine. Doesn't it just look like its so much more nice to your joints? And it IS! My bestie Heather also loves it. That's two raving reviews coming from these two Mommies! I won't say its easy but it is gentle and it burns twice the calories that the typical machines do!
