Short and Effective, Amazon review of Sara Holliday’s Prenatal Yoga DVD May 8, 2007 By Whitedimond (Germfask, Michigan United States) – I love this DVD because I can do it in the morning before work. It’s short enough and easy enough to do at 5:30 AM. I would not advise doing this DVD while pregnant with a full stomach. That’s why I prefer this in the morning on an empty stomach.
