Core strength will help not only with the physical stuff like back pain & posture. Core strength also helps provide the strength to say no, the knowledge to know when we need a rest. Yoga helps us turn our focus inward, to our core. Developing core strength helps us to act on the knowledge that we find! Maybe I dream big, but I also understand that each person whose life I can open to this possibility of feeling better from the inside out, to practicing yoga, means my dreams have come true.
