Pelvic Stabilization #16 is described as which exercise?

• A. Arm Press
• B. Single Leg Extension — jumpboard
• C. Ribcage Stabilization
• D. Single Leg Lift — jumpboard

Answer: (B)

Pelvic stabilization means keeping the pelvis square and level while the legs move, so the core and hip stabilizers work to prevent rotation or tipping. The Single Leg Extension with a jumpboard fits this focus perfectly because you extend one leg against resistance while the pelvis must stay braced and steady. That opposition of the leg against the jumpboard creates a clear demand on the deep abdominal muscles, obliques, and hip stabilizers to maintain a neutral pelvis throughout the movement. The jumpboard adds external resistance and feedback, making maintaining that alignment more challenging and thus training pelvic stability more effectively. The other options don’t target this control in the same way: Arm Press centers on the arms and shoulder girdle, not pelvis stability; Ribcage Stabilization focuses on keeping the ribcage still rather than the pelvis; Single Leg Lift — jumpboard involves lifting the leg with movement that doesn’t stress the same leg extension against resistance while preserving pelvic alignment as directly.
