Hello NB! Whitecap fan?
As to your question, if you don't feel you need a rest day, then don't take it as a general rule, but your question is a bit ambiguous. Do you mean one rest day a week, or are you saying no rest days at all?
I'm going to assume you mean should I take a rest day in between shoulder and back day, so something like Mon, Tues, Thurs, Fri lifting each week. SO therefore your question would be you don't want to take Wed. off.
Sure, that would work, especially if it fits your schedule better. Space your routines out as they fit you.
BUt it is important to know that rest and recovery is as important as the lifting itself.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
