Performing the: A Step-by-Step Tutorial Cable Seated Overhead Curl
Sit on a bench facing the cable machine, grab the bar with an underhand grip (palms facing towards you), and keep your hands shoulder-width apart.
Lean slightly back and position the bar at shoulder level, keeping your elbows close to your head and your back straight.
Slowly curl the bar towards the back of your head while keeping your upper arms stationary, only bending at your elbows until you feel a full bicep contraction.
Pause for a moment at the top of the curl, then slowly return to the starting position, controlling the weight on the way down to complete one repetition.
