In Pelvic Stabilization #13 Parallel, what happens?

In Pelvic Stabilization #13 Parallel, what happens?

• A. Basic parallel jump with feet hip-width, knees tracking forward, pelvis quiet.
• B. Jumpboard work with heels together and toes apart.
• C. One knee pulls toward the chest while the other leg jumps.
• D. One leg extends while the other jumps.

Answer: (D)

Maintaining pelvic stability during an asymmetrical leg movement is what this item emphasizes. In this variation, one leg extends while the other leg jumps. This setup challenges the body's ability to keep the pelvis level and the spine neutral while the limbs move in opposite directions. The pelvis must remain quiet—no tilting or twisting—as you coordinate the hip and core muscles to control the movement. This is why the described pattern—one leg extending while the other jumps—is the best fit, because it directly tests stabilization under unilateral leg action. The other options describe movements that are symmetrical, use a different setup, or involve different leg actions, which don’t reflect the described pattern.
