Yin yoga was developed to penetrate deep into connective tissue expanding flexibility while invigorating the energy centers of the body (nadis) to release blockages and increase your energy flow.
Focusing on static movement, breath work (Pranayama) and meditation to create a profoundly deep and rewarding practice. The primary differences between Yin Yoga and many other forms of yoga is that you are encouraged to not use your muscles and passive poses are held for several minutes.
Without the distraction of constant movement and muscle engagement, your connective tissue has the opportunity to stretch and you are able to go much deeper into a pose. Static stretching is excellent to increase range of motion.
Therefore, if you are tight due to repetitive movement from other sport activities or your day job keeps you in the same position 8 hours a day or your body has aged (because yes it will do that) – Yin yoga will help stretch it out.
Yin Yoga is also great for reducing stress in the body and mind. Holding poses without distraction for several minutes teaches us to relax. We begin to release tension that is deeply engrained in our muscles.
