I'm interested in this b/c after a long hiatus I'm back to lifting but am using dumbbells for bench rather than barbell/smith b/c it appears to help with some sore shoulder issues - I can get the dumbbells down closer to my chest with far less shoulder strain/pain than I could with barbell.
I'm doing 55 dumbbells, sometimes 60's and trying to figure out what that equals in barbell weight. What leads you to this 145=45/50 correlation?
thanks

It's emperical and not extremely scientific but although in a barbell bench press you are lifting the bar, its contribution to the overall stress on muscle fibers is less than the plates that are on each side. That said, barbell bench press (especially with a narrow grip) will work the center of the chest a bit more. I would say 55 lb dumbells on the bench is pretty similar to 155 or so on the bench, though although as I said before, there are different groups of stabilizing muscles being worked by dumbbells and less work being done by the middle of the pectorals, at least IMO.
