Tension Climbing’s Grindstone board is an optimal training pick for the general climber looking to find strength gains through hangboarding. The Grindstone offers slightly deeper edges than the Grindstone Pro.

Comfortable jugs over the top will help you get warmed up and edges ranging from 50mm deep to a mere 15mm will ensure a full range of finger strengthening.

And if timing your workout, you’ll find a convenient phone slot right on top.
