Hip internal rotation (IR), the femur’s ability to rotate inward in the hip socket, is a critical yet often undertrained movement in runners. During the stance phase, hip IR allows the pelvis to stabilize, absorb load efficiently, and transfer force effectively through the lower extremity. When IR is restricted, runners often compensate with increased trunk and pelvic rotation, or by overloading the knee, and lateral hip tissues, which contributes to chronic tightness and injury. It has been lin

Internal hip rotation is a key part of preparing the body for birth. But how we access that rotation matters. Most of what’s taught focuses on femur-on-pelvis rotation—like turning the thigh inward or cueing “knees in” while seated. That can be a helpful first step, but it’s not the full picture. 👉 The real goal? Training pelvis-on-femur internal rotation. This is when the pelvis moves over a stable femur—like in a hip shift or asymmetrical lunge. This version is far more functional: it mimics

Internal Rotation (IR) The arm and forearm whip through release using natural internal rotation of the shoulder. This creates more speed, spin, and efficiency with less stress on the elbow. The follow-through allows the arm to decelerate naturally (typically down and across the body). Hello Elbow The pitcher forces the hand up to the shoulder after release, often restricting natural whip. This can reduce speed and spin and place more stress on the elbow and shoulder because the arm is stopping a
