This is kind of directed to people who know a little bit more about muscle physiology than “lift heavy and eat”. I am trying to approach this from a standpoint that is as far away from the 17-year-old-flex-reader as possible.
First off… I dont read flex.
Now, lets start getting deep. I am currently taking physiology in college and we just covered a topic called “hebbian synapses” involving neurons. The basic principal says that “If you don’t use it, you lose it: Use it more and it gets better”. It is the reason you forget some things and remember others… Think “Out of site, out of mind”.
Applying this to weight lifting, we always here about “overtraining fatigues your nervous system”, but this new information I have learned appears to contradict that. It seems that the more you use it, the better it gets(this has been proven)… So where does “overtraining” start? Obviously we know that you can hurt yourself and strain things, but as far as the nervous system is concerned… what does it take? Or is that a myth?
