You should consult your physician or other health care professional before starting 75 hard. Don't get yourself out in the middle of a thunderstorm when there's lightning coming down. In 70 fiveday, which is such a short time to gain what this programme will give you, you will feel like a different person in all the right ways. If you miss any of it, i mean just part of any of them, you have to start over at day one. So let this programme do its work. Commit to it and see it through.
