Set an appropriate weight matching your fitness level. Stand directly in between the uprights and grasp both cables. Take a shoulder-width position, keep your torso upright and your pelvis is in a neutral position. While bending your elbows to 90 degrees, extend both your hands. Elbows, shoulders and hands are in one level on a vertical axis. Your palms are facing forward.
Lead your motion above your head along vertical line. Elbows are still slightly flexed even in the top position. Go back to the starting position in the same way by bending your elbows. Eliminate going much lower than to shoulder level with your elbows. Exhale as you go up and inhale as you go back to the starting position. Keep your wrists firm without any rotation.
Make sure you keep your torso straight without arching your lower back. Your pelvis is in a neutral position.
Avoid engaging the trapezius muscles (lifting your shoulders).
Keep a correct elbow angle when going back to the starting position.
Avoid dorsal flexion (bending backwards) in your wrists as a result of greater resistance.
As you start, choose an appropriate resistance to master the technique well.
If possible, perform the exercise in front of the mirror and watch to make sure your shoulders, elbows and knees – basically your whole body – are in the correct position.
