I went to a new yoga class on Friday morning, and it was GREAT. She put me through moves I've never tried before, and while we were doing it, I thought, "Wow, this is pretty hard", but I wasn't dieing or anything. When the class was finally over, my legs and arms were shaking.
But Friday night, I could hardly move. My legs were so sore, I didn't know if I was going to make it. OWWWW!
By Saturday I was ok. Sore, but a good sore.
And just another note on the subject of OW....Transformers are the absolute worst thing to step on. Worse than legos or any other toy I can think of. We only have one transformer (thank goodness!) but it seems to always be in my path. We may not have that one for long.
