Reply to comment by Ohgodgethelp in Why does mild compression lead to paresthesia but not paralysis? by Hola3008

Stronger muscles != stronger nerve signals.

But X muscle fibers working at 85% efficiency > 3X muscle fibers working at 85% efficiency, so someone who works out may find they're less noticeably hampered by the loss in muscle strength, since they had more to spare to begin with.

True, but does using those muscle groups then trigger nerve growth in order to up the fiber recruitment? Obviously there is going to be a falloff in nerve growth as one ages, just like everything else.

I can help (multiple spine issues).

I was big, now im just a little big, but can do the same weight for the longest. Now that it's been a few years of compression I am noticing fatigue doing 'common' things like holding arms and shoulders up too long - yet can still do the heavy weight. So - it's complicated! My first spine doc visit schedule this week. But more or less the size goes real fast, and the strength far slower.
