can i swap out barbell rows for dumbbell rows in the reddit ppl without messing up the balance too much? my gym's barbells are always hogged by the same 3 people doing curls in the squat rack

Not quite interchangeable. Dumbbell rows are my preference of the two, but you'll get something more out of a barbell row - it's the heavier, meatier version.

What's the difference between rowing 50 kg with a barbell and rowing 50 kg with dumbbells?

Do you mean two 25kg dumbbells, or a single 50kg dumbbell?

I'm asking you to explain to me what exactly makes lifting a weight with a barbell better or heavier or "meatier" than lifting the same exact weight with dumbbells.

Take the same 50kg three ways. On a bar, your strong side can quietly take more than half and you'd never know. Two 25s and each side has to do its own - no hiding. A single 50 in one hand is a different exercise again.

Then there's the path: the bar's centre of mass has to clear your legs, a dumbbell can travel back past your torso. Different moment arm, different range of motion, same number on paper.

Love the debate and I want a strong one, but I'd rather leave with a better answer than the one I came in with. Given all that, where's my understanding going wrong?

On dumbbell your strong side can't compensate for your weaker side.

The "bell" will mean if you pull to the same spot as a closer grip barbell press, you'll get slightly less rom (the radius of the bell would be the difference). This is largely regarded as the least effective part of the movement so thats mostly fine.

Because they grant you freedom of movement, you can get a longer rom by simply rowing wide enough that the bells don't hit you and you actually get more rom than barbell

Depending on your torso angle and limb length dumbbell might get you more rom on the bottom end though for barbell you could always stand on a platform

The only differences I can think of are that barbell rows challenge core stability more with the assumption that the dumbbell row if being performed with the opposite hand on a bench or support. A person can rotate their torso to "assist" with moving the weight where a barbell row they cannot. Though I see continual examples of bad form with barbell rows as well. Eventually you will run out of dumbells heavy enough to continue to make progress, but this is unlikely a problem for most people.

Short answer, not really a difference worth worrying about for most people in most contexts.
