About the Y&Y Alien
The YY Alien is the perfect pre-climb warm-up tool and post-climb strength maintainer. Even if you're not a climber, it is great as a simple and handy muscle exerciser for your fingers.
The Alien creates resistance when squeezed and activates the flexors and extensors of the fingers. Slip it in your pocket and use them on the go for some quick resistance training while you visualise your next project.
Also ideal for muscle recovery and injury rehabilitation, the Y&Y Alien is a great finger strengthening tool and a resistance trainer for both climbers and non-climbers alike.
