Thats intresting. I havent seen someone do it like that before except on a preacher bench or with a barbell.

You rotate the dumbell because most people have the bells starting at the sides and then rotate it. when you have the big dumbells its impossible to start the movement as you described without the pop pop of a strained tendon/bicep - at that point if you have the bell with your hand faceing up your placeing a masive stress on the bicep.

ofcourse 10kg dumbells you wont notice the problem but when it gets heavyer - the weights that will produce real growth and not just for poseing in the mirror it will be a real issue.

this is how i would think a dumbell curl should be.. well maby a bit faster.
