Flexibility training - Most value for time for the advanced climbers

Most advanced climbers are very close to their physical peak when it comes to maximum strength and endurance. Surely, the advanced could improve a bit if they spend another 100 hours which possibly could mean they could do their project. However, based on the knowledge that the #1 rock climbers, Adam Ondra and Ashima Shiraishi, are also possibly the most flexible advanced climbers out there, it might be better to invest the extra hours improving your flexibility rather than your strength. When you come to the regular 8a climber, I bet, training flexibility is at least ten times more effective rather than doing another campus or endurance session. (c) Pavel Zvire
