Query: The most helpful exercises a pregnant woman can do.

I had never done yoga before trying this, and found this deck to be both simple to understand and very relaxing. You can choose the complexity and length of your workout with different combinations of cards (if you went straight through the whole deck it would take more than 2 hours). It's small enough to take with you even to the hospital, and the breathing and relaxation techniques are very helpful for preparing for labor. Of all the pregnancy exercises I have tried this is by far the most rewarding, and I intend to continue it even after I am no longer pregnant.
