In Pelvic Stabilization #15 Single Knee Extension, what happens?

• A. One leg extends while the other jumps. Keep the extended leg long and stable.
• B. One knee pulls toward the chest while the other leg jumps.
• C. Jumpboard work with heels closer together and toes apart.
• D. Knees track forward while the pelvis remains still.

Answer: (A)

The move tests how well you keep the pelvis stable while the leg works to extend. In single knee extension, you lengthen the working leg to create a long, supported line, and the other leg stays in a controlled position to help keep the pelvis level. The emphasis is on maintaining that long, stable extended leg so the pelvis and spine stay aligned rather than tipping or twisting as the knee extends. This controlled setup trains coordination between the hip, abdomen, and back to protect the lower back and maintain neutral pelvis. That focus fits the idea of extending with length and stability rather than curling the knee toward the chest or shifting the pelvis. It isn’t about jumpboard positioning or a specific toe- or knee-alignment cue that would imply a different movement pattern. The key is keeping the extended leg long and the pelvis steady while the other leg provides stable support.
