Golden Grip 3-Piece Stress Ball Set

With these stress balls you train the pinching movement of your hand. A strong grip is of great importance for a lot of different sports (climbing, calisthenics, powerlifting, judo, etc.), but also very useful for everyday life. That jar of applesauce that always cost you so much effort to open is suddenly a lot easier! In addition, a strong squeeze is one of the best indicators of vitality and life expectancy, even better than blood pressure!
