Using a wrist trainer strengthens the hands and improves grip power. Using the device is especially suitable for those of you who practice acrobatics, aerial acrobatics, handstands or juggling. Take the ball in your palm and rotate your wrist so that the inner ball starts spinning. Smooth gyroscopic motion keeps the ball steady in your hand, and the resistance needed to spin it increases your strength and endurance. At slower speeds, the resistance is lower, at higher speeds you can generate up to 15 kg of gyroscopic resistance. Comes with a wrist strap to prevent the ball from falling out of your hand.
The compact ball is easy to carry with you wherever you go.
The Pro Model includes an LCD screen to monitor your progress and create tests of strength challenges. Extra features over the Classic version include total accumulated revolutions, real-time revolutions, the highest RPM and physical strength index.
