Need to workout

I never thought I'd ever ever say this but I really need to get to the fitness center and work out.  These interviews (10 so far) are very tiring mentally.  My body really wants to go and lift weights, do some biking, do something other than sit.  I'm hoping I can squeeze  an hour in today during our supper break.  I find it utterly fascinating that that this is my mindset.  For so many years, I never ever thought of exercise except as a chore, must walk to lose weight, etc.  But now it's something I actually crave.  Who'd have thunk it?
