most will probably think this is a stupid question.. becuase it is. So go easy on me.
OK, why does the weight seem heavier... when I have 2 20 pound weights on the dumbell, than when I have 4 10 pound weights on the dumbell?
The 20 pound weights are longer of course.
I did weigh them.. and they are roughly the same.. But I have to take off 5 pounds of smaller weights when using the 2 20pounders, to do the same amount of reps. I did with the 4 10 pounder.
Anybody notice this?
Depending on the type of 20-lb plate, the moment of inertia could be greater on the larger weight than the smaller 10-lb. weight. If you supinate the weight during the movement, this could come into play.
To clarify, you mean barbell right? The long bar that you put plates on is the barbell, fyi.
I've never even seen a 20 lb plate. Are you sure they aren't 25s?

i dont think he means barbell, he means how long the bar is that the weights are on, compare a 20lb dumbel to a 100lb dumbell the 100lb one is longer. Atleast thats what I think hes trying to say.
But how does he put four 10 lb weights on a dumbell?Originally Posted by XxH0LyWaRsxX
There ARE dumbells with detachable weights. They are in essense really short barbells with really strong clamps. I have a set at home (which I never use).

I mean dumbell,
yeah I'm over here in Germany so we got weights in KG.
really its 10KG weight = 22 pounds
and 5Kg weights = 11 ponds.
But I just simplified it.
My dumbell is not even so long.. actually quite short. What so hard about putting on 4 10lb weights? 2 on each side. Plus I can fit a 2 5 pounders also.Originally Posted by ABDomega
Ok, I was just thinking of basic equipment, not the kind of DBs where you can attach additional weight. Sorry for the misunderstanding, I can't help you.
