1. Hand Jamming

In this video we review the “hand jam”. Hand jamming is a technique used to climb cracks as opposed to featured faces or slabs.

This technique requires the climber to place their hand into the crack and tuck the thumb into the hand to create a narrow (karate chop shape) or wide (cup shape) hand jam, depending on the width of the crack (see above video for demonstration).

Two methods for using a hand jam include:

Thumbs-up – In this method, your palms are facing inward and your thumbs are up. This version of the hand jam allows you to move greater distances between jams.

Thumbs-opposed – In this method, your thumbs are pointed down, palms outward. This may feel more solid since the meat of your lower thumb is the lowest friction point; however, the distance you can move between jams is less than with thumbs-up. This is because the orientation of your shoulder joint in this position creates a slightly more limited range of arm motion.

It’s likely that while you’re climbing, the rock may dictate which method you end up using at times, but feeling comfortable with both methods is key for successful crack climbing.

A few considerations when applying either method of hand jamming include:

1. Look for constrictions in the crack which match the shape of your hand.

2. When possible try to hang with straight arms to save your arm muscles, but be sure your shoulder blades are set down and back to protect your shoulder joint! Don’t just hang like a sack of bones—use your skeleton to support you with good posture and alignment.

Please remember, climbing is inherently dangerous. Climb at your own risk.
