The reaction ball is a 6-sided ball that bounces randomly in unpredictable directions and heights. This helps to increase reflexes to develop qualities such as coordination, agility, reaction speed and concentration. Used in physical preparation, it is ideal for maintaining reactivity and for training in baseball, football or any other sport. It can be used alone, against a wall or solid surface, or as part of a team. It is made of high quality rubber, which allows it to maintain its appearance and training characteristics for a long time. A fun way to improve speed and agility.
