Day 13

Cardio Power & Resistance today...I took more breaks than I should've, because my lower back/tailbone was hurting. It doesn't hurt all the time, just when I move in certain ways. That's enough to disable me, because Insanity moves every part of my body. There's Pure Cardio + Cardio Abs tomorrow, which is certain to be hell. I really need more sleep, as staying up late is making me really tired.
