ok, so when working with z bush and you are sculpting something, but then you start to run out of geometry and you start to get stretching, how do you personally get passed that or not run into it at all?

Dynamesh is great for evening out geometry.  I usually clone the tool so I won’t lose what I’ve worked on. Then you can project the higher detail and control that by masking.

If you don’t want to use dynamesh, you can hide part of the mesh, and press ‘divide’ and that will only subdivide the area you are hiding.

I retopo later anyway so I’m not too concerned with topology.
