The 9c Climbing Test Calculator
What is this Test?
The 9c test was a test developed by Stian Christophersen and Martin Mobraten, and largely popularized by a video posted by Magnus Midtbo, Stian, and Martin on YouTube. It is a test developed for approximating what grade you are strong enough to climb. It is a good benchmark to see if you are significantly weaker in one of the 4 tested areas, but does not address the many other factors involved in climbing. Stian and Martin have also published a book "The Climbing Bible" which, among other things, discusses the many other factors in climbing performance.
What does it Test?
The test has 4 components:
- The first is the maximum weight you can add to a 20mm edge hang (on a fingerboard, generally in a half-crimp position) which approximates your finger strength.
- The second is a "one-rep max" pull-up which approximates your maximum "pulling" strength.
- The third is a core strength test. You can do one of 3 positions (bent-knee L-sit, full L-sit, or a front lever) and you hold the position for as many seconds as possible.
- Lastly, the fourth exercise is a dead hang which is just how long you can hang on a pull-up bar. It should be noted that for this exercise you should not move/adjust/shake out your hands once the exercise starts. This test approximates your endurance.
The Test
Please Note: You can enter either kilograms or pounds and it doesn't matter because the scoring on the "weight added" tests is based on the percentage of weight.
