Every individual climber will have some specific area of their climbing that holds them back. For many it is fear of falling. For others it is lack of tactics and strategy. Maybe it’s just an inability to try hard. Some climbers have terrible footwork, others lack sufficient upper body strength. Maybe a climber fails because they hold on too tight, or can’t pace themselves.
Whatever the specific area is, each individual will improve their climbing the most by targeting that weakness. However, if we examine climbers as a whole, is it possible to distinguish one area which is the most important? A single factor that if improved, will yield paralleled improvements on real rock for every climber? I say there is. I say there is one particular thing that is the most important. A factor that separates the elites from the rest of the pack. It is any area that every climber will benefit from training . I’m talking about finger strength.
