Just a couple of things to note;
The hand behind the head thing is to show you that the bicep is only fully contracted in that position and that cramping occurs because you've never fully contracted the bicep, which is another topic for another day.
two primary functions of the bicep is to supinate and to raise the arm over your head.
To find the right width for curling, place both hands in the contracted position, as if you standing there with a barbell.
your hands will be slightly wider than the shoulder and not inline with the elbow, this is the safest width to curl, any narrower or wider will place stress on both the shoulder and elbow, continued use will fuck you up.
the curl is more than just a bicep exercise
a good goal to reach would be 60kg x 12.
do that and I guarantee you'd be very strong and flexible
