Performing the: A Step-by-Step Tutorial Preacher Curl
Pick up the barbell or dumbbells with an underhand grip, ensuring your hands are shoulder-width apart.
Slowly curl the weight up, keeping your upper arms and elbows stationary on the pad, until your biceps are fully contracted and at shoulder level.
Hold the position for a second and squeeze your biceps at the top of the movement.
Gradually lower the weight back to the starting position, maintaining control and resisting the pull of gravity. Repeat the exercise for the desired number of repetitions.
