I have found one. Let me preface this by saying if you were not working out before your BFP it may be too hard for you. I found a great DVD on Amazon called Summer Sander's Prenatal Workout. It has workouts for each trimester and an express workout. I did the second trimester workout this morning and I am shaking from it. It was a total of 50 minutes. Its mostly lunges, squats and arm exercises, all you need is a resistance band.
Re: If anyone is looking for a good Prenatal exercise DVD...
Hey i just noticed that Netflix has this DVD so if someone has Netflix connection you can order it.
Netflix is also having many more Prenatal workout DVDs. I am so stupid i did not realize it should check on netflix . It has a collection of breastfeeding and Child CPR videos. I was about to join a class for this but now i am rethinking . I will at least watch the dvd first before i enroll for these classes.
