@moveu: Your hips aren't just along for the ride. They're the connection between your upper and lower body. Every step, squat, pivot, and turn depends on them rotating well. Limited hip rotation changes how force moves through your body. The low back twists more. The SI joint works harder. The knees and ankles lose options. Even the glutes stop doing their job as well. That's why we don't just train strength. We train hip rotation. Because better hips give the rest of your body more ways to move.
