Thread: Bar or dumbell?

Which do you guys think is more effective for bench and how do the weights differ, for example 45lb dumbell on each side would b equivalent to doing how much on the barbell, seeing as they are quite different, is it directly comparable (aka adding the weights and comparint the net mass on each)?
thanks

I feel that dumbbells are much more effective than barbells... for the right exercises. For example, if you do dumbbell presses, you'll have a much greater ROM than a bench press, and you'll use more stabilization, and develop those oh-so-important stabilizers more than you could have had you bench pressed.

As for a formula to turn one weight on dumbbells into a certain weight on the barbell, there isn't one . However, you can typically do far more on a barbell than with dumbbells (again, that's with certain exercises, like DB presses vs. benching).
