I used this during my pregnancy from the third month to the day before I delivered. All the poses shown were very useful when I delivered my baby - they worked the areas of my body that were most needed durning labor. They also kept my muscles toned so I believe following this DVD made my recovery faster. Excellent choice and I would recommend this to any woman who is pregnant.
I bought this for my first pregnancy and just dug it back out for my second. Wonderful, easy-to-follow modifications for all three trimesters. I always felt wonderful after each workout.
