"Corn" boxing bags and balls, originally made from small bags filled with dried corn, are among the oldest boxing equipment and provide unique training benefits. Compact and easy to deploy, the "corn" boxing ball allows you to practice shear punches to improve defense and upper body movement. For the best training experience, we recommend using dried chickpeas as a filler. Alternatively, you can use fillers such as rice, shredded cloth, plastic balls and of course dried corn. Adjust the amount of filler material to achieve your preferred weight and density. If you want to use a different type of filler material not listed here, be sure to contact our customer service for the best advice!
