How do we grow? My theory:
When you damage yourself, your body learns to re-build itself, and become STRONGER than it was before [super-compensation].
Don’t be afraid of damage or pain
interesting with weight lifting:
You are intentionally trying to damage or “tear†your muscle fibers, in order to stimulate your body’s growth hormones.
Why I love feeling sore the day after
“DOMSâ€â€” delayed onset muscle soreness. It seems to be a good sign that we had a “good workout sessionâ€.
I find this interesting, because bodybuilders LOVE the feeling of DOMS. In fact, when we no longer feel DOMS, we get concerned or worried that “we didn’t push ourselves hard enoughâ€, or the workout was too easy.
Seek the micro-trauma

Too much trauma is bad. But small doses of trauma are good — which are a stimulus to growth. Micro trauma:
Small doses of trauma which stimulate growth.
The tricky thing is this:
Knowing the dose.
For example, what’s the line when beneficial micro trauma (hormesis) is good for us, and when too much trauma can destroy us (beyond repair?)
