This is my second yoga dvd that I have tried in addition to attending a regular yoga class. The other I used was a prenatal yoga dvd during my 4th pregnancy. Now that I am 5 months post-partum, I was looking for something more challenging that I could incorporate into my weekly exercise routine of running and weight training. I find this dvd somewhat challenging. He moves through the poses rather quickly and I would prefer to hold them a bit longer. However, he gives you a decent yoga workout in an hour which is nice for a busy mom of 4!
