Professional Ski Instructors of America (PSIA) Level 2 Practice Exam

Counter-rotation describes twisting the upper body in one direction while the lower body turns the opposite direction at the same time. This opposing rotation lets the skier create balanced, connected movement and better edge control, helping initiate and finish turns smoothly without forcing the skis to twist independently. It keeps the upper body aligned with the fall line while the hips and legs contribute the opposing rotation needed for precise steering. The other terms refer to different body movements or technical ideas and do not capture the specific opposite-direction twist of upper and lower body.
