Dynaflex Pro Plus Gyro

Unlike outdated hand grips, the Plus Gyro targets most muscle groups from your fingers to your shoulders. Comfortably set your own paceā€”the harder you work the more resistance it provides with gyroscope technology. And it doesn’t just provide a great workout for your arms, but helps you prevent carpal tunnel syndrome.
