>>914020there's a couple disciplines involved, more if you include social interactions
>climbing>safety system intro to /out/ climbing I would suggest "traversing" a foot off the ground, it will allow you to familiarize yourself with how "you fit with the rock" while allowing you to simply step off upon failure
now, combine that discipline with, let's say, a mattress that you need to accurately land on in case of a fall, making sure to land in an uncompromising position where you do not cause your body any acute stress
A more complex version of this would be to use a "line" or "rope" instead or combined with a "mattress", with your main concern, just like the mattress technique, in being to avoid acutely compromising forces, such as a situation where the rope is "wrapped around you unnecessarily" turning you into a fucking dreidle. With modern textiles, concern of severing a "rope" is nill, unless there is literally an arrowhead esq piece of rock stabbing at the cord. See "vector forces" for reference to safe loading of "rope system" and "building of anchors"
Just remember, a hundred years ago, we grabbed a "rope" in our hands, while it was tied around the waist of our peer, and that technique is still valid today, all of the rest is just mandatory mechanical advantage to adhere to the modern complacency.
