I love rock climbing! Very little actual experience but always jump at the opportunity to pull some plastic!
The most impactful advice I got early on was to make sure you rest with legs bent and close to the wall and straight arms and not the opposite. And if you plan on sticking with it, learn different holds early because it will help you avoid injury as you increase frequency and difficulty.
Resting with legs bent and arms straight definitely makes sense. I found myself doing this naturally today.
I just looked up different holding techniques during climbing. I had no idea this was so crucial. Thanks for the advice! :)
