Gyro ball

So what exactly is Powerball? In a nutshell, it’s a great forearm-strengthening device: it’s excellent for strengthening the fingers, wrist, and forearm muscles—and, last but not least, your grip. Thanks to its unique design, it provides effective strengthening benefits that can be utilized by weightlifters, rock climbers, cyclists, tennis players, golfers, squash players, and even musicians. Increased strength, endurance, and dexterity come in handy in every area of life.

How does it work? A very clever little mechanism is the heart of the whole system: it’s essentially an internal rotor that moves the fingers and wrist without overloading them. This means it not only helps train wrist mobility and flexibility but can also be extremely beneficial for rehabilitation purposes (after injuries). Thanks to the resistance generated as the rotor spins, the faster you spin the ball, the greater the resistance it provides, thereby increasing the muscle workout! This allows for a specific strengthening of the forearm muscles that is precisely tailored to your current fitness level.
