I've often been advised to train my legs, the biggest body part, before I eat a ton of carbs so I was originally planning on training my legs on Thursday which is my carb nite. But I want my shoulders and back to grow the most. Should I do my shoulders and back on Thursday? Or just throw in some rows and shoulder presses to my leg routine and continue on with my training schedule as is?

I currently train legs on CN, myself.  That was simply how my routine ended up when mapping it out for recovery (based on certain pairings, like Chest / Biceps day).  It will switch-up in a week.The reason you've been advised what you have re: legs, is b/c legs take a LOT out of you, back being the next most-taxing bodypart.You could move your Delt/Back to CN, or you could keep Delt/Back day a couple days away from Thursday (for recovery purposes), and toss in some key growth moves for both on Leg Day (1 move ea.).  If you do the latter, I'd suggest standing overhead barbell presses (for delts) and bent-over rows or deadlifts (for back), then proceed w/ leg work.Two splits you could use:*if training Delts/Back on CN:M - Quads / Hams / CalvesT - ArmsW - restT - Delts/BackF - restS - ChestS - rest*if training Delts/Back on another day, with exercises on CN:M - Delts/BackT - ArmsW - restT - Quads / Hams / Calves w/ 1 move for Delts and 1 move for Back @ beginning.F - restS - ChestS - rest...threw that together quickly, you could work it out however you feel is most efficient for your recovery abilities.Cory
