Scott said, and he made me feel very flattered, "Your legs must be like two outboard motors by now." I am here to tell you this kind of thing has upsides and downsides.
MAJOR UPSIDE: Today I did my first spinning workout in over a year. (The last time was back when I was first having shoulder problems, circa March 2007.) Let me tell you: all that kicking has paid off! It was much easier to do the Stand Up Sit Down Fight Fight Fight thing that you do in a spinning class, thanks to my legs of steel. I know I will be stiff tomorrow, because this is the first cycling I have done since spring break, but STILL. I was pleased by how hard I could work and still walk after. (And I do know that it is possible to overdo it in a spinning class. I had a blast at my first ever spinning class--about 12 years ago--but I could barely stand afterwards, and I am not exaggerating. It took me about 2 weeks to be able to walk without screaming.)
MAJOR DOWNSIDE: Most of my pants fit more tightly than they did back in my sedentary phase over the winter--through the thighs, I mean. I attribute this to the tenaciousness of my leg flab, and its desire to keep my leg muscles hidden. Luckily I am a big fan of wide-legged linen pants, and those never stop fitting!
