It's a pain in the legs.

YC warned me that the soccer moms would kick my butt, but I went ahead and did it anyway. Spin class was rough. Pedaling hard wasn't an issue, but the two minute long stand & pedal portions of the class were painful. I wasn't really hurting after the class was over, but it certainly felt bad at the time. I'll probably go back again.

Oh, one more thing. I've got a surprise coming at the end of the month. Keep your eyes peeled.
