Adjust the cables on both sides to be as low as possible. Grab the opposite grips with your hands to cross the cables. Move slightly forwards and stand straight.
With a slight bend in your arms bring your elbows upwards to approximately shoulder height. Then slowly retract to just before the start position. Maintain a consistent bend in the elbows throughout. Your elbows should stay roughly in line with your hips on the way up and down. Repeat for the desired amount of repetitions.
Avoid hinging from the hips to help raise the weights upwards or lifting your hands too far above your shoulders.
