Finger lock, hand jam, thin hand, fist, butterfly, arm bar, chicken wings, off-width…
These terms—progressively wider—describe the various body positions we use to wedge ourselves into cracks, engaging every limb to maintain grip and move upward.

Join us for a two-morning or full-day workshop focused on crack climbing techniques, held at a sport crag featuring natural crack lines.
We’ll cover essential safety aspects, including how to place removable protection, retreat using cams (friends), and build solid placements.
