Well… usually (at least in my circle of climbers) it revolves around two things…. The amount of time the participants spend away from home, coupled with a very high and real risk of death….We know that proper strength and conditioning training is good for you and that it's also possible to push it too hard. See: Hormesis. Might the same be said of climbing, IOW, a moderate amount of it at a moderately challenging level of difficulty is good for you, but more might be detrimental to health?
Add to that the time spent training for (or to avoid) that outcome…
