Well, I have now completed one week of this routine.
I'm doing 4x6 and have substituted bb bench press for weighted dips.
I've really enjoyed this routine, and have fantastic doms (you know the constant ache in your lats and middle back, triceps feeling
really tender, and the strike of pain in your pecs every time you take a step down a flight of stairs!

).
I was a little sceptical about my tris getting done, as I used to do a similiar routine to "Pull day" anyway, but I included narrow dips and skulls. I shouldn't have worried, the doms have led me to believe that they've had enough stimulus.
My bis never feel like they're being done though, but they haven't for ages to be honest. When I work my back, i'm pretty good and isolating and contracting my back muscles to make sure that it IS my back that's taking most of the load, and my arms just end up being 'hooks' if you know what I mean, without taking much of the force. This seems to result in my arms never feeling like they're being done. Yeah, I know it's not all about feeling, and I'm trusting that they're 'getting it' too. -- The same story goes for my calves.
Anyway - just wanted to say cheers Frankie for a very enjoyable and well thought out routine. (Lets hope it bears some fruit!).
