My first yoga experience

I did the P90X Yoga X program last night; it definitely shattered my expectations of what yoga was all about. I admit it is all new to me, and I could definitely feel it in some of the weird postures that you go through during this 1h30min session. I did not think I would sweat that much! I got a few leg cramps, in the quads, upper legs, and sides too.
The good thing is I can only get better on this one.
