Cathe, in a very early weight-lifting video: "Some days you're really strong, some days you're not having it all there - it all depends on what you ate, how you slept, what's going on in your life..." and she goes on to explain that after she's been up at night with her crying baby (this shows JUST how long ago this was
) the next day she has "no strength". I think of this when I'm trying to cut myself some slack, during a workout or really during any activity.
