Performing the: A Step-by-Step Tutorial Cable Preacher Curl
Sit on the preacher bench, aligning your armpits with the top of the bench, and grab the bar with an underhand grip, keeping your elbows close to your body.
Slowly curl the bar up towards your shoulders while keeping your upper arms stationary, exhaling as you perform this movement.
Hold the contracted position for a moment as you squeeze your biceps.
Gradually return the bar back to the starting position as you breathe in, ensuring that you fully extend your arms and the biceps are fully stretched.
