Your psoas muscle is a strong hip flexor that is difficult to release when there is any mental agitation, especially when working with twists. Tune into this muscle and learn alignment techniques that help you discover more refinement in moving your hip joints and pelvis. Warm up with sun salutations before deeply exploring postures like revolved parsvakonasana and matsyendrasana. When your psoas is released, twists become comfortable, deep and integrating forms within your practice.
