In some cases dumbbells will give you a better range of motion and help develop smaller muscles.
Another common addition to 5x5 I've seen is adding a dedicated core day (weighted ab crunches, hanging leg raises, planks)
Core is the 2nd most important part of doing pull exercises (after back)
This has always smelled like broscience to me. I guess I'm just skeptical that someone unable to create stable positions with a fixed object (barbell) will have more success creating proper stable positions off of objects that move freely. Based on what I've seen in the gym, it looks like the barbell users usually end up 'collapsing' into stability... then again, most of what I see in the gym are meatheads using way more weight than they should be. Maybe it would be different if priority was given to proper mechanics rather than pressing till your eyeballs bleed.
What does that mean? If your goal is to get stronger you have to lift as much weight as possible. Obviously you don't want to hurt yourself, but the emphasis on perfect form over heavy weights is "broscience" if your goal is strength.

The whole point is that it's more difficult to maintain stability with dumbells.
No need to miss out!
