While observing high school students lifting dumbbells overhead and performing full squats with hips dropping below the knees on each repetition, which action by the teacher would be most appropriate?

• A. Coaching the student to limit knee flexion to no less than 90 degrees
• B. Encouraging deeper knee bend
• C. Stopping the session immediately
• D. Praising the technique as is

Answer: (A)

Controlling how deep the squat goes is key for safety and proper technique when lifting overhead. When hips drop below the knees on each rep, the knee bend becomes deeper and the torso must work harder to stay stable, which can increase stress on the knee joint and the spine, especially with an overhead load. Coaching students to limit knee flexion to at least 90 degrees (keeping the thighs roughly parallel to the floor or above) helps keep the movement within a safer, more controllable range while they build strength and mobility. This approach prioritizes control, spinal alignment, and joint health, and can be adjusted as the student gains proficiency. Pushing for a deeper knee bend would raise risk, stopping the session immediately isn’t necessary if technique can be corrected, and simply praising the current form would overlook an unsafe depth.
