1 - Attach a straight bar or short handle to a low cable pulley and sit or kneel facing the machine.
2 - Hold the attachment with an underhand grip, palms facing up, and rest your forearms on your thighs or a bench with your wrists extending just beyond the edge.
3 - Keep your elbows and forearms stable, shoulders relaxed, and allow your wrists to extend slightly downward under control.
4 - Curl the attachment upward by flexing your wrists, squeezing your forearms at the top of the movement.
5 - Lower the attachment slowly back to the starting position, maintaining control and tension on the cable.
6 - Repeat for the desired number of repetitions without letting your elbows lift or your forearms move.
