Query: Rocki's Prenatal Yoga, Vol.1

This was the most boring yoga workout that I have ever seen. If it's not bad enough that you're tired from being pregnant, this DVD puts you to sleep. I understand that yoga is supposed to relax a person, but this is severe boredom. The poses are not being held long enough to receive the benefits of the stretch and the routine itself is long and drawn out.
