Why is the hook grip commonly used in Olympic lifting?

The hook grip is commonly used in Olympic lifting primarily because it provides a stronger and more secure grip on the barbell. When performing lifts such as the snatch or clean and jerk, the hook grip allows the lifter to wrap their fingers around the bar and then hook their thumb over the fingers. This configuration creates a firmer and more stable hold on the bar, which is crucial during dynamic movements that require a lot of force and control.

With a secured grip, lifters can maintain better form throughout the lift, minimizing the risk of the bar slipping or shifting in their hands. This grip is particularly advantageous when lifting heavy weights since it distributes the load more evenly across the fingers and reduces reliance on sheer grip strength, which can fatigue more quickly. Consequently, using the hook grip enhances performance and increases the potential to lift heavier weights safely.
