The YY Alien helps prevent injuries by balancing the tension between the flexor and extensor muscles of the fingers, with added bonuses of improved grip strength, stability, and accuracy. Offering three varied resistances, it's also an ideal choice for rehabilitation purposes and warming up the fingers and forearms pre-climb.
