Query: not the best for fitness or pregnancy

This video offers very little to women trying to modify their exercise routines appropriately for pregnancy. As other reviewers have mentioned, almost all exercises are performed on the back, making it useless except in early pregnancy. While it may provide some benefits to women in early pregnancy or postpartum, it is not rigorous enough for women who are already fit and hope to maintain their fitness levels. I found that there were too few reps of each exercise to provide me with any real benefit. I have had more success modifying the exercises in regular yoga and pilates videos.
