We tend to practice falling, or anything stressful, to get it over with. This will not only delay our learning of the skill but will also cause us to learn it incorrectly. Our body will learn to tense up. Learning how to fall means we learn to remain relaxed while falling. Here is a learning-based approach to practicing falling.
1. Small increments:
Begin on toprope
First, simply hang on the rope and swing around.
Second, take toprope falls
Third, take lead falls
2. Gauge for learning: Comfort
First, stay at the same increment until you are comfortable
Second, you know you are comfortable when…
B: You’re breathing throughout the fall
E: You’re looking down during the fall
R: You’re relaxed throughout the fall
P: You’re arms are out; not grabbing the rope
3. Belaying: Giving a cushioned catch
First, do not progress to lead falls until your belayer learns how to give you a cushioned catch during toprope falls.
Second, a cushioned catch is: the belayer gives in to the pull when you fall. Your belayer should end up about five feet off the ground when your fall is ended. If he isn’t, then he will need to push off as the rope becomes taut. This will be a learning process for your belayer.
