This is the 8th exercise from Kriya for Immune Fitness, an excellent kundalini yoga set for the lymphatic and nervous systems. In this exercise, breathe in and out though circled lips. Inhale as you squeeze the elbows close to the ribcage, exhale punching out to the sides. The thumb is placed inside fists. Add the mental mantra, thinking to yourself Sat (truth) on the inhale, Nam (identity) on the exhale.
