Performing the: A Step-by-Step Tutorial Cable One Arm Preacher Curl
Position yourself in front of the cable machine, facing away, with your arm resting on a preacher bench and your hand gripping the handle, palm facing up.
Keep your upper arm and elbow stationary, curl the weight while contracting your biceps, continue the movement until your biceps are fully contracted and the handle is at shoulder level.
Hold the contracted position for a moment as you squeeze your biceps.
Slowly begin to bring the handle back to the original position as your breathe in, keeping the tension on the bicep muscle. Repeat for the recommended amount of repetitions and then switch arms.
