When your workout needs to be really tough and must succeed, the medicine ball is the tool you can trust. With a medicine ball, you can optimally train your entire body while significantly improving your coordination, endurance, and strength stamina. The medicine ball is made of polyurethane-coated artificial leather, making it ideal for exercises where a firm grip is essential. Especially for circuit or core exercises like the "Russian Twist," it is crucial that you have full control of the ball and can choose between different weights. The ball is filled with silk cotton and rubber particles, so it won't be damaged if it happens to fall to the ground. Conveniently, the weight in kg is printed on the ball, along with the Gorilla Sports logo, so everyone knows where you got your equipment for building muscles.
