The Grindstone Pro follows the no-nonsense design of the Grindstone, but with smaller edges and pockets for more advanced hangboard training. The asymmetric edge layout keeps the edges spaced more consistently and each edge depth is laser engraved so you always know what you’re hanging on. Super comfortable jugs for pull-ups and lock-offs? It’s got those too! As well as a phone slot on the top of the board to keep your timer pointed at you for the duration of your workout.
