The problem with working out

Feeling pretty crappy today. Not sick, just blah. I blame working out. You see, I haven't worked out since Friday and I've felt progressively worse everyday. That's the problem with working out, you have to keep doing it. You can't just workout whenever. You get used to that endorphin high and all that stuff. Then you don't get the good feeling and then it just drags you down. Don't start working out unless you have staying power. I'll be working out today at lunch so we'll see if my theory holds water. Whatever that means.
