Ouch

So, I went back to the gym this week. well, back to a gym which technically I'm going to for the first time since it just opened.
At any rate, today I went to do my normal routine and started on an elliptical. Only to discover that it wasn't an elliptical. it was a cross between an elliptical and a stairclimber that was ment to torture your entire lower body. But, rather than stop, get off and look like an idiot, I kept going.
Now I'm having trouble sitting down, standing up and walking.
