Adjust the cable to be as high as possible and hold the grip in one hand. Position your elbow in front of your hip and start with an arm bend of 45 degrees.

Start by extending the elbow until its straightened then slowly retract back to the start position. Keep your elbow in a fixed position and your torso should remain still throughout. Repeat for the desired amount of repetitions then switch sides.

Avoid using excessive momentum and allowing your elbow to move around too much.
