Hip Extension

The exercise is intended to improve hip extension capability. Improved hip extension allows gradual movement toward a fuller stacked half-kneeling position. Coaching cues are used to stop the hips from moving out of extension during the slam. Many rotation findings may be misleading or resolve once true hip extension is restored. Restoring full hip extension often resolves frontal and rotational limitations without directly treating those planes. The movement constitutes a posterior pelvic tilt and low-level glute bridge, not a full hip thrust. The article distinguishes true hip extension from lumbar extension as a critical clinical distinction. A stacking problem in half kneeling is not always caused by poor effort or poor cueing. From the loaded position, the athlete drives the arm back as if pushing the hips rearward. From the tucked position, the body walks out along the roller until the hips approach near-full extension. The hip extension position is maintained isometrically throughout the entire breathing sequence. Rolling the arms out occurs once the hips reach the extended position. Breathing is performed while holding the hip extension position, making that position the c…
