Y&Y tool to work on your antagonists. In climbing we keep using our flexor muscles of the forearm and often forget the counterpart, our extensors. This imbalance can cause injuries. That is why you need the Alien in your tool kit. Not only will it reduce the risk of injury but it will also significantly increase your general finger strength and even precision.
Different strengths: Easy (Green), Medium (Blue), Hard (Orange)
