In contrast to the dynamic forms of yoga, Yin yoga does not focus on strengthening your muscles, but on relaxing them.
By relaxing your muscles you reach the connective tissue, located in the deeper layers of your body. Connective tissue strengthens and extends slower than muscle tissue, hence Yin Yoga poses are held for three to five minutes. Yin yoga provides deep relaxation, stimulates your meridians and organs and teaches you to experience space in your body.
Pay attention with Yin yoga if you are pregnant or have just given birth. Always let the teacher know. Since your body is soft, it can be harmful to go deep into the postures.
