Explode into a high intensity workout with the Cortex Wall Ball 28kg Complete Set. Wall ball training involves highly explosive movements that target broad muscle groups and get your heart pumping. They improve your functional strength and are a great way to burn calories. A huge range of exercises use wall balls, but typically they are thrown against a wall in a way that activates the whole body. Because of their purpose, wall balls need to conform to certain standards in order to maximise your efficiency. All wall balls are 35cm in diameter, and the benefit of this is that you can maintain a consistent grip regardless of the ball's weight. Our wall balls are constructed with a soft PU leather shell that is comfortable to use, even when an intense workout makes your palms sweaty. You can trust in the durability of our design; our quality stitching will see you through use after use. Even weight distribution throughout our balls makes throwing and catching easier and safer. With our complete set of 4 wall balls from 4kg - 10kg, you're sure to find the right challenge for any workout.
