What is the role of the hips in a Clean?

In the Clean lift, the role of the hips is crucial for generating upward force during the explosive extension phase. As the lifter begins the movement from the pull, the hips are utilized to create momentum and power through a powerful extension. This explosive hip extension is what allows the barbell to be propelled upward, enabling the lifter to transition the bar into the front rack position. The synchronization of the hips with the rest of the body—such as the feet and shoulders—ensures that maximum force is applied efficiently and effectively during the lift. This upward force is essential for overcoming gravity and achieving a successful lift. The correct execution of this explosive movement is what ultimately contributes to the overall success of the Clean.

The other options do provide some relevant functions during the lift, but they do not capture the primary role of the hips in generating the explosive power that is characteristic of an effective Clean. Maintaining balance, flexing to lower the bar, and stabilizing the weight are important elements in the weightlifting process, but are secondary to the primary action of hip extension to drive the barbell upward.
