Pelvic Stabilization #15 is which movement?

Pelvic Stabilization #15 is which movement?

• A. Single Knee Extension — jumpboard.
• B. External Rotation Closed — jumpboard.
• C. Parallel — hip-width apart.
• D. Single Knee Pull — jumpboard.

Answer: (A)

The key idea is maintaining a steady pelvis while the leg works against resistance. In a knee extension performed on the jumpboard, you press the board away with one leg while the torso stays aligned and the pelvis stays neutral. This setup forces you to stabilize the pelvis to prevent rocking or tipping as you extend the knee, so the movement trains pelvic stabilization directly. The other options describe different leg positions or actions that don’t place the same demand on keeping the pelvis still while extending the knee, so they don’t illustrate this stabilization cue as clearly.
