In order to get better as a climber, you need to work on strengthening your grips. The Duonamic Powrhold has you covered. It is a grip strength trainer that you can take with you anywhere to train. You can adjust the position of the rope into different grooves and change the angle of your grip.
Powrholds are ready for pinch, sloper, judge, and edge grips. They have a texture that feels like a rock but goes easy on your skins.
