Stretching Yoga for pregnant women is a great way to get you in the habit of stretching before every class. When I first started doing yoga, I did not stretch as much as I should have, and this led to some muscle and ligament problems in my lower back and a big butt that I could not get around. After I got my yoga groove on and started doing a few more stretching sequences per week, things began to improve, and I was finally able to get some much needed down time after a long semester of school. Stretching is always a good way to start any new exercise routine, and if you have not been stretching lately you may want to start now..
