Supine Hip CARs are a foundational mobility drill designed to restore clear, controlled movement at the hip joint without compensation from the spine or pelvis. Working in an open-chain position allows you to isolate the hip capsule, refine neuromuscular control, and gently explore available range without load or momentum. This practice emphasizes slow, intentional circles within the smallest range you can fully control. The goal is not to chase depth, but to improve joint clarity and coordination. Keep the pelvis heavy and quiet, move smoothly, and prioritize quality over size—because consistency and control are what create lasting mobility.
