Performing the: A Step-by-Step Tutorial Barbell Biceps Curl

Continue to raise the weight until your biceps are fully contracted and the bar is at shoulder level while you hold the contracted position for a brief pause as you squeeze your biceps.
Now, inhale and slowly begin to lower the bar back to the original position.
Repeat these steps for the desired amount of repetitions of your workout routine.
