I want to know which movement has an effect on which muscles. In a very simple but accurate way.
I don't know of any muscles that people never
use; at least, my gross anatomy professor didn't mention any.
They are all there for a reason, and you need them to get yourself from (lay -> sit) and (sit -> crawl) and (sit -> pull-up) and (sit -> stand) when you are an infant.
You can, through extended convalescence, de-activate certain muscles
in your back.
There are certain muscles that work intrinsicly with other (primary) muscles, but you are not consciously aware of activating those muscles when you use the primary muscles.
What's back there, no pun intended, is a very long list
You'd be surprised, if you took a body apart over the course of a (summer) semester, what's in there.
I can try to answer any questions you have concerning specific movements that site lists, or different synergies that occur when certain muscles are activated. The back is really too complex for me to try to go through it all here.
