The RETRO SERIES Double End Ball is a training aid that is designed to develop hand-eye coordination and reflex speed, which are crucial skills for those who practice boxing or other martial arts. Although it may take some time to master, this equipment is an essential part of a comprehensive fitness training program. To optimize your training sessions, it is recommended to position the ball in a way that allows for a full 360-degree rotation around it, as this will also help to improve movement and balance.

Made from genuine cowhide leather, the RETRO SERIES Double End Ball is suitable for intermediate and advanced level workouts due to its reduced surface area, which makes it more challenging to hit. Its smooth surface and consistent machine-stitched seams ensure that the ball is cylindrical and streamlined, providing a more realistic training experience. The sewn-in rubber bladder has a valve that significantly reduces air loss, ensuring that the ball continues to perform effectively. However, to maintain the product's performance, it is recommended to regularly check the inflation of the ball. The rebound speed of the ball can be adjusted by adjusting the tension of the straps.
