The GyroTwister and Gyro Twister Xbeam is the training device that's addictive - in a positive sense: The latest tests from Germany show that training with the GyroTwister significantly improves your grip.

It also trains your lower arms, upper arms and wrists in a fun and effective way. GyroTwister doesn´t operate using weights and springs like other types of training equipment, but by using the principle of gyro power.
As a result, the power of GyroTwister is variable and always can be adjusted to the training condition of the user.
