DVD question

Body: 

On the intro to the dvd, it says not for use for women who are menstruating. Why is that?

In other medical systems, such as Ayurveda, it is thought that steep rises in intraabdominal pressure, through such things as heavy exercise, can cause menstrual blood to reverse and flow back up through the tubes resulting in nodes of endometriosis implanted outside the uterine cavity. Steep DECREASES in pressure, as in the stomach lift, are very risky during pregnancy.
