CuraBall Hand Trainer New Customer Reviews Each CuraBall Hand Trainer is constructed with a heavy-duty internal rotor made from high-grade zinc or steel, which provides the necessary mass to generate significant gyroscopic torque as it spins. This rotor is housed within a rugged, impact-resistant shell that is encased in a premium, non-slip silicone grip, ensuring that the device stays securely in your hand even during high-intensity sessions where sweat might otherwise cause a slip. This means you never have to worry about replacing batteries or finding a charging cable; as long as you are using the CuraBall Hand Trainer, the screen will provide you with real-time data on your current RPM, the maximum RPM achieved, and the total number of rotations during a session. Weighing in at approximately 0.66 lbs, the CuraBall Hand Trainer strikes the perfect balance between being lightweight enough for portability and heavy enough to provide substantial resistance, capable of generating over 60 pounds of torque at peak speeds.
CuraBall Hand Trainer New Customer Reviews This design philosophy extends to the safety of the device as well; because the resistance is generated by the user's own movement, the CuraBall Hand Trainer is inherently self-limiting. For those who travel frequently, the CuraBall Hand Trainer is the ultimate portable gym; it takes up less space than a tennis ball and can be easily tucked into a carry-on bag, briefcase, or gym locker.
