This seems to be a recurring theme. Lesson: lots of things that seem fun at the time result in varying degress of pain and inability to move very fast later. Not that there's anything wrong with that...especially if you can sit around on Sunday afternoons.
Yesterday we did the 100 push up challenge. Not as hard as it sounds. We also, over the course of an hour, did 200 squats and 200 crunches, in addition to several other strength building exercises. This was followed by an endurance brunch, where only the strong hung on to the bitter end. We got more than our money's worth of bottomless mimosas. Ridiculousness ensued.
For the record, I'm mostly blaming Rob for my current state, and not factoring the bottomless mimosas into the equation.
