Why not put in rows, pull-ups and all assistance work in a seperate workout
Put allll the curls into another workout which is at least 48 hours after the pull workout. I wouldn't be able to curl for shit after back day.
Just looks like your exercises are all over the place. Why so many exercises? Do you really need 3 row variations? Why aren't leg curls after sumo deadlifts? Why aren't leg presses in the same workout as squats? Why doesn't it look like you're targeting chest, while doing tris/shoulders twice a week? Where's the shoulder work?
I'm doing the following split right now. I love it, because effectively I hit each bodypart twice a week while focusing on every bodypart once a week:
Day 1 - Quads, also hits hams, lower back, glutes
Day 2 - Chest and bis, also hits shoulders, tris
Day 3 - Posterior chain, also hits quads
Day 4 - Shoulders and tris, also hits
Day 5 - Back, Traps, also hits posterior chain and traps
This split is pure genius. I believe someone suggested it when I was looking for a split myself, and now I can't imagine doing anything else but this.
Final comment.. I would find it hard to progress on 3x8's, I think. I quite enjoy 5x5's, and other lower rep/higher set combos, as the first and main movement for every workout. Give it a try, you might love it too.
