I answered your burning questions

Hello Cracksters

You guys are doing an amazing job at helping spread the jamming joy around the world. Small things that we do collectively helps bring crack climbing to more people…

…which is why I opened up our last newsletter to you guys, to ask me your burning questions, so we can share more knowledge and experience between everyone.

Massive thanks to all the questions that came in, sorry I can’t answer all of them. I’ve picked 3 which you’ll see below

 

Question 1

My worst crack size is 0.75. Too thin for thin hands and too wide for fingers. I've been working on finger thumb stacks. Do you have any advice to make these stacks more solid? Also, are there any other techniques I should consider for this difficult size?

Answer…

This is classic ring lock size, and in all honesty it can feel desperate. A few things I try to remember when climbing this size: Actively push with the tip of the thumb into the crack wall. Often when I’ve done lot of Ring Locks the tip of my thumb will be quite sore and start to build a skin callus (which indicates how much I’m actually pushing with it) When you pull the fingers down on top of the thumb, remember to flex at the finger tip (i.e. bring the tip towards the palm) to make the pulp around the knuckles expand. Keep the forearms inline with the crack and close to the rock. Really really work those feet. with the correct pair of shoes the toe jams can actually be reasonable on this size.

 

Question 2

After a weekend of offwidth climbing I am often covered in bruises. Anyway to prevent this? or is this an indication of good or poor form?

Answer…

My first answer to these questions are, cover up before you start crack climbing and not after/during. So many times I see people start crack climbing they damage their skin, then they decide to tape up…it’s too late at that point 😅

Also think about what body parts you will actually be using for your offwidthing. For example if you’re doing vertical armbars, chicken wings or squeeze chimneys there will be a lot of skin contact; so use long sleeves shirts/trouser (with friction material), tape down the ankles of your trousers, use ankle protectors and neoprene elbow/knee pads under your clothes to prevent pressure wounds. If you are climbing an invert stacking offwidth, realistically you may only need to tape your hands/wrist and protect your ankles. Full body protection isn’t actually necessary. protect what is needed and not more.

In answer to the second part of the question, if you are covered in bruises (unless you have done many metres of offwidthing) it generally means that technique has started to fail. This could be for two reasons.

  1. You get tired. Everyone gets tired offwidthing, and when you get tired your technique decreases. When technique decreases you end up scratched and bruised. So increasing physical ability will help here.
  2. You have a lack of knowledge. If you aren’t using the correct techniques at the appropriate times, and technique fails again you end up scratched and bruised. So increasing knowledge and practice will help here. 

But, let me point out that technique failure isn’t always a bad thing. If your technique is failing due to trying hard and getting tired it means you are pushing yourself, which ultimately is a good thing and how you improve.

 

Question 3

Climb slower with tricky-to-set bomber jams vs climbing faster with not so bomber jams on long routes?

Answer…

Interesting question. In general I always like to climb a little slower and take my time in setting good jams. The reason being that climbing on not-bomber-jams for many moves in a row can end up with you eventually not being able to set any jam at all and falling.

However like with all these things, it really comes down to the climber, the climb they are on, and their ability. If the technical level of the jams are below the standard of the climber, then they have a large margin for compromising the jam. So, taking less time to set the jams and climbing faster won’t actually have that much of a negative effect.

Don’t waste your winter gains
Hey Cracksters, Ok so maybe I’m a little early with this one, but we had one nice day of weather and it reminded me that climbing outdoors does still exist! So let's go through 5 key points which will help the transition from indoor winter training to outdoor spring goals really easy (by the way I understand some of you will be on the other side of the world, so will already be out and about in...
Want to learn jams quicker? Do this
Hey Cracksters, As we know you're going to be getting out there and crack climbing with the new gloves, I want to focus our attention today on the three big jamming types—hands, thin hands, and fists. I see people get confused all the time about what they should work on or how they should prioritize practicing each jam. So, today we’ll look at the basic jamming hierarchy.   1. The Perfect Hand ...
Is Taping a Waste of Time?
Hey Cracksters, This week I’m going to answer a question I get asked a lot… "Pete, should I be using tape or gloves? Which one is actually better?" It’s a classic debate. Here is my honest opinion The Case for Crack Gloves Speed: You can take them on and off in seconds. No more 15-minute taping sessions at the base of the crag (and then having to keep the tape on all day) while you...
