The final hand jam trick you missed
|
Hey Cracksters, Weâve been banging on about the basic hand jam technique for ages 1. the 'L-shape' 2. Thumb towards the little finger 3. Brace with straight fingers across the crack But in step 2 there's a subtle movement that adds that extra 10% of âumphâ making your hand jam wider and more solidâŚand like most hand movements in crack climbing, itâs all about the thumb.

Lets make your bomber hand jam even betterâŚ
Lets go through those steps
1. The L-Shape
If you havenât heard us talk about the L-shaped starting position for a hand jam, then you obviously havenât watched or read enough Wide Boyz content
Before you put your hand into the crack, make an L-shape to make your hand as thin as possible before you insert it.
2. Thumb movement
For the next step of your hand jam we always say, push the tip of your thumb into the centre of your palm and towards your little finger. This expands and hardens the pulpy part below the thumb itself, and gives the hand jam some width to fill the cracks space
Now THE EXTRA TRICK: Instead of just leaving it in this position, push the tip of your thumb down towards that pulp (so now your thumb should have a bend in its joint). This little extra movement does 2 things:
1. Helps harden the thumb pulp even further
2. Ensures the tip of the thumb is out the way of the fingers for completing step 3. If you leave your thumb straight you wonât be able to do the âfinger barâ motion effectively.
3. Finger Bar
Finish the jam like you normally would, by pushing the tips of your 4 fingers across to the opposing crack wall.
Happy jamming,
