Spinal twists towards the right and the left, is part of the 6 movements of spine, in this picture – The chest stays neutral ( though it’s working completely ) and the movement for a twist is coming from the hip. It’s like squeezing a wet towel to drain water and when u let go, the towel flares, the same scenario with the spine, here the deeper the spinal twist and breath the more space it flares to the Center of our body from the top of the head up down up to the tail bone !! Twists juices up your spine and brings you right back to the moment of presence. U can say it’s kind of mood booster.
