Performing the: A Step-by-Step Tutorial Barbell Standing Back Wrist Curl

Slowly curl the weights while contracting your forearms, keeping your hands shoulder-width apart.
Continue to raise the weight until your biceps are fully contracted and the barbell is at shoulder level. Hold the contracted position for a brief moment as you squeeze your biceps.
Slowly begin to bring the barbell back to the starting position as your breathe in. Repeat this movement for the recommended amount of repetitions.
