Enhance grip strength: The weightlifting fitness booster hook is designed to greatly enhance grip strength, allowing you to lift heavier weights, which is essential to increase the effect of strength training. 2. Improve stability: Booster hooks increase stability and control by dispersing weight, which not only helps bodybuilders lift heavier weights, but also helps prevent injuries caused by excessive twisting or lifting. 3. Reduce arm fatigue: Since most of the weight is borne by the booster hook, the fatigue of the arms and hands will be greatly reduced. In this way, the user can have more energy and stamina to focus on exercising and improving strength.
