Consult with your doctor to make sure that you are clear to exercise.
Be careful when you work out. If something doesn't feel right, stop and consult an expert.
Don't go on any extreme nutritional or exercise programs that are going to be damaging to your body or your health. Consult a physician if necessary.
Use your head. Think about what you're doing and make sure it makes sense to you. If it doesn't, get clarification.
Ultimately, you are in control, and you are responsible for what happens to your body.
I think that those are pretty straightforward things that should go without saying. However, we live in a letigious society and due to this fact I enclose the following disclaimer:
