Next up in our bouldering jargon busting series are J words… Jugs, Jams and Jumps! 🦘⁠

See all the previous letters through our blog feed. Now let’s explore what J is for…

JUG

An excellent handhold, easy to hold onto.

JAMMING

The technique of inserting part (or all) of the body into a crack. Thin cracks take fingers, wider cracks take hands and fists, and offwidth cracks devour arms, shoulders, knees, feet and legs and spit them out covered with rash.

JUMP

A dynamic movement in which one hand stays on while both feet leave the rock. There is at least one point of contact at all times.

JUMP START

Jumping from the ground to the starting holds of a problem.

Watch out for the rest of our alphabet dropping soon.
