Query: Vinyasa Yoga Short Forms

I purchased just the Vinyasa Short Forms DVD and the option of choosing 15 or 30 or 45 minute workouts has been great. I started with the 15 minute routine and worked my way up from there. Also very helpful are the labor poses that were demonstrated. This Vinyasa Yoga has definitely helped with my back pain and I was glad to have some kind of safe exercise program I could do while pregnant. Jennifer Wolfe also explains the modifications for the 3 different trimesters, so you can practice this form of Yoga from your 1st month to your 9th month of pregnancy or anywhere in between.
