Overwoking the back?

[SaiBoT]

I'm 290 and working on 297 lbs...and my routine is focused around bench press, OHP, squats, and deadlifts. Hard to go wrong with those!

You have almost more 100lbs than I do and I will take any advice from you because even more because of your type of training!

Here's what I would recommend:

Deadlifts 5 x 6
Dumbell rows 3 x 6
Seated rows 3 x 8
Weighted pullups (wide grip) 3 x 6
Narrow-grip pulldowns 3 x 6

Also, I consider the traps to be a muscle on its own, so I work it out with the shoulders.

Always try to lift as heavy as possible with proper form...less reps if need be.

Good routine, only thing i would change is the rep range. Since size is your goal here. Go heavy on the deads are rows, try pyramiding up the weights:-

Deads 5 x 10, 8, 8, 6, 4
Barbell Rows 4 x 12, 10, 8, 8
Chins 3 x 12, 10, 8
Cable Rows 3 x 10, 10, 15*
Lat pulldowns (narrow or reverse grip) 3 x 10, 10, 15*

* = back off set. The idea is to lower the weight and get a few more reps to pump the muscle full of blood. I wouldnt add any trap work to this day, try hitting them with shoulders for a while and see if that makes a difference.
