Your pelvis and sacroilliac (SI) joints carry the weight of your upper body and are also responsible for distributing force to your lower body. Lack of support here can affect so many other areas, especially your back and hips. Strengthen the muscles that support you with this sequence designed with your pelvis and SI in mind. Work with active supine movements, supported poses and standing balance postures, to help create more overall stability and strength. Props Suggested: A block.
