Shiva Rea has designed a prenatal yoga video to help you gain all of the amazing health benefits yoga has to offer. No matter which of the routines you do, be sure to end with the guided meditation to gain the full benefits of this special yoga practice. If you are new to yoga, feel free to only work fifteen to twenty minutes a day. Then, in a comfortable way, add more time and variety to your practice. Three instructors present modifications of the routines for the different trimesters.
