Which stretch involves drawing a knee toward the chest while the other leg remains straight on the ground?

• A. Flexion
• B. Extension
• C. Single knee to chest stretch
• D. Windshield wipers

Answer: (C)

This question tests your ability to recognize a named stretch from a specific body position. In this stretch, you lie on your back and pull one knee toward the chest while the other leg stays straight on the ground. That exact position is the single knee to chest stretch. It’s a common way to lengthen the muscles of the lower back and hips and to relieve lumbar tension, with the straight leg on the ground helping to stabilize the pelvis. Flexion is a general movement term describing bending a joint, which doesn’t name the stretch itself. Extension is the opposite of flexion—straightening a joint—which doesn’t describe pulling a knee toward the chest. Windshield wipers involve rotating both legs side to side with the hips stabilized, not the one-leg-to-chest position described here. So the described maneuver is best identified as the single knee to chest stretch.
