I can agree with that to some point but take a metal rod ad shove it threw your leg after doing a marathon and let me know how ya feel about working hard right after
Ah, you just hit the appropriate stresser (depending on whom you talk to) when you mentioned the marathon.
It's like the debate, wind on the plants or not? Wiggle them around or not? In my experience with things like trees (I'm leaving that cut of AC/DC out of this discussion, that girl is just WEAK, nothing I did got her stronger) if you tie them up and support them constantly, you're always going to have to and can expect some other problems to pop up. Instead, let them experience snow load, let them experience wind, etc, and you'll get a stronger plant.
I mean, quite literally, stress is one of the huge drivers of evolution, right? :D
Now, I've never done what's being discussed here, honestly because I didn't think there was anything to it. But I'm willing to keep my mind open.
