Keeping your hands over your elbows, start by spreading your arms out to the side and rotating your palms until they are in line with your body, at the height of your shoulders and palms facing forward. Maintain a relaxed shoulder while driving the weight overhead until your elbows are fully extended.
Pause at the top position for a 2 sec count while maintaing tension in the arms and trunk.
Lower the weight under control until your elbow is bent to 90 degrees, at the height of your shoulders. Your hands should be located directly above your elbows. Bring your arms together in front of you until the dumbbells are in front of you at the height of your forehead. Remember to breathe normally throughout the entire movement.
Repeat steps 1 through 4 until you have completed the desired number of Arnold press repetitions before resting.
This completes one set of Arnold press.
