Performing the: A Step-by-Step Tutorial Dumbbell Alternate Biceps Curl
While holding the upper arm stationary, curl the right weight while contracting the biceps as you breathe out. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a brief moment as you squeeze your biceps.
Slowly begin to bring the dumbbells back to the original position as your breathe in.
Repeat the movement with the left hand. This equals one repetition.
Continue alternating in this manner for the recommended amount of repetitions.
