Insanity!!!

I took my first "insanity" class in Tuesday, and.... Wow! It really did feel a little insane while I was in the class. If you've never done it before, it's a series of not-very-complex calisthenic exercises that you do at full intensity for short bursts of time, interspersed with even shorter bursts of rests. At the end of it, I felt spent! But when I walked outside, the birds all seemed to chirp a little more, the sun seemed to shine brighter, and I realized--I was actually experiencing a workout high. And that actually made it worth the workout!
