Functional jump height is a crucial metric for athletes in sports like football, volleyball, basketball, soccer etc.. Jump Ball provides a unique way to measure and improve this aspect of performance by allowing athletes to practice going up to catch, hit, or head a real ball suspended in the air. With the built-in measurement system, athletes can track the height of their jumps and train to increase their functional jump height. The patent-pending magnetic system adds resistance to the ball, requiring athletes to exert force to interact with it, revealing their true strength in the air. Jump Ball offers a glimpse into the future of functional jump training, empowering athletes to reach new heights in their performance.
