I was so excited to try out this video, but I have to say I was very dissapointed. After the reviews I read I thought this was going to be a good workout. I don't think I broke a sweat once during the entire thing. I could have folded the laundry and had a better workout. I was 17 weeks when I tried this and running has become difficult with all the trips to the bathroom and some round ligament pain. I think this video is meant for people who eiether have never done any type of exercise before or who are in their 7th or 8th month of pregnancy. I am used to running about 20-30 miles a week so if you are expecting a good heart pumping workout from this you are going to be very dissapointed. Go for a fast paced walk instead. The quality of the video was fine and the music did not bother me. I have also purchased the video with Karen S, but have not tried it after I wasted 40 minutes on this one.
