All the exercises you've ever seen or done somehow stemmed from our body and mind's need to follow its natural biorhythms.
You don't need all these exercises. You just need to heal your own biorhythms, learn to feel them and gather your range of asanas with the help of the teacher.
At our seminars you learn to understand how your biorthythms function within the body, define practice intensity by yourself and start your own collection of exercises. You don't have to attend this course permanently, once is enough. Only those who wnt to adjust their practice and learn new asanas come again.
Outside Astroyoga© I mostly prefer power classes or stretching or relaxation at the table of Swedish massage therapist. But all this is just an additional range I use when feeling that a certain group of biochemical processes needs more attention.
