Mostly a good list, but my personal experience would contest the one about not working out on an empty stomach. Working out shortly after a meal was usually pretty miserable for me, since so much energy was being put towards digestion and sometimes I'd get nauseous. I find I have much better focus and more energy on an empty or nearly empty stomach. Depending on the time of year, I prefer working out on an empty stomach (in summer) or at least 1 hour after a light meal (in winter).
