Keep the elbows and forearms still.
Extend one wrist while flexing the other, as if rolling up a newspaper.
Alternate hands back and forth, rolling the bar steadily.
After a set, reverse the direction by leading with wrist flexion.
Breathing: Breathe steadily throughout; avoid holding your breath.
Only the wrists move
