During Ribcage Stabilization #5 Knee Changes, what movement is described?

• A. The arms reach forward while the torso twists.
• B. The hips pivot while the knees remain bent.
• C. One knee comes toward the chest while the other leg extends over the footbar, switching legs while maintaining curl and rib stability.
• D. The arms circle over the head while the legs stay still.

Answer: (C)

Ribcage stabilization with knee changes trains you to keep the upper body quiet and the abdominal curl intact while the legs move through a knee-change pattern. The movement described—one knee coming toward the chest while the other leg extends over the footbar, then switching legs while you maintain the curl and keep the ribcage stable—captures that idea: the legs are changing positions, but the torso stays steady and the ribcage doesn’t twist or flare open. This shows controlled leg work without losing trunk control, which is exactly what this exercise cue is aiming for. The other options introduce twisting of the torso, hip pivots, or arm movements that don't align with keeping the ribcage stable while the knees change.
