Am just wondering, doing 40 LB dumbbells is equivalent to about how much weight in terms of bench press. I assume 80 pounds right?

A pound is a pound whether it's attached or not.

Its easier to bench a bar than the dumbbells.

Basically this. Not exactly sure that there is an exact numerical ratio of difficulty per pound though.

40 lb dumbells for flatbench press?

You can probably bench about 100 lbs.

This isn't really true (not really wrong either). It depends on your technique and whether one side is stronger than the other.

Actually, it is. Balance is practically done for you with a bar. Same can't be said for dumbells.

I'm aware of this. But I still think it depends on your technique and balance. I rep 155lbs 4x12 on a bar. I can also do the same sets with 75lb dumbells. Yes there is a slight difference, but for most people it's not really going to be huge.

Yeah, it is a difference, but not as large as I would expect even for well developed technique. How hard are you pushing yourself with these sets? Do you feel a difference in difficulty with one over the other? I would imagine that your max bench would be well over double either of your individual arms.

These are basically upper body burnout days. Honestly Dumbells tend to be more difficult because i usually go with more of a "fly" motion to get angles that a bar doesn't get. But that's kinda the point: people need to switch up exercises to get the most gains.

I agree entirely with the switching up.

Uh. Dumbbells aren't "harder" in terms of lb for lb weight. They are harder because you fatigue faster expending more energy setting the weights up, keeping the weight stabilized and balanced (more so when new to em). You can get used to it definitely but if you are newbie it won't be the weight that is the problem, its finishing your reps. Just do it for a week or 2 and you should be fine. Gains on dumbbells are superior to bars.

It's worse if you don't have a spotter because then you expend energy getting the weights just into position and then you end up doing less reps. But you aren't doing too heavy of weight it seems so shouldn't be much of an issue for awhile.

They don't equate to anything. It just depends on how strong your chest is and how strong your biceps are. I can bench over 200 but only do about 55 max on biceps but I've seen some people bench a little over 100 and do 50 on dumbells. It really varies with everyone.

You will do a lot more weight in bench press than dumbbell press.

I don't recall a bench being associated much with bicep It's tricep, delts and chest ...very little bicep (only long head) but not much at all.. I bet your tricep and delts are a stronger than a guy who can bench 100...or else you are doing something wrong, no offense.

Put some weight on a barbell and find out yourself.

I didn't say they were associated at all. :? My post may not have been clear but I kinda gave examples that disproved how they relate to one another.

I'd say the ratio is about 80%, in other words you can dumbbell press about 80% of the weight you can bench press. A person who can dumbbell press 80 lbs should be able to bench about 100.

...no, it's not. At least not as far as muscle growth and development. Dumbbells are much more difficult to lift (lack the bar to stabilize the weight and you can go lower). From my experience, I think a good 'rule' is that you just take the bar out of the equation...45lbs dumbbells = 45 lbs on each side of the bench...but that is nothing scientific...just how it 'feels' when I lift.
