Hey guys Im new here and am I glad I found a wrestling forum!

Ok so my question is when you are shooting is it better to back step then penetrate or simply just penetrate. Cause I have seen both and am wondering is it due to different situations etc.

Also when you take a back step, do you just step back a couple inches or is there angles. I know back stepping is to change levels and it also loads your shot but am not sure on proper technque. Thanks in advance for the replies/answers.
