Since the people on this site are the ONLY ONE'S who can answer questions , here goes.

First of all ,many thanks for ALL the help you have given me it tweaking my program. I was totally wrong in my thinking about the triceps ladder.

With that in mind, a question. In doing a behind the back shoulder shrug, if you lifting your hands to waist level, would it then become a triceps exercise?

Salvatore,

I would have to say no to this. Tricep exercises are all pushing movements in one way or another. The shrug behind the back is a pulling movement. It primarily works the trapezius muscles.
