PERSONAL TRAINER INSTRUCTION :
Begin this exercise standing upright with your stomach braced. Hold the weight or bar in front of your body and pull the weight up by shrugging (lifting) your shoulders up.
Shrug the weight up through the shoulders but do not bend at the elbow. Exhale as you pull up and do not lean towards the weight. Keep your stomach flexed through the entire exercise.
Do not perform this exercise if you have shoulder or back pain. Pick a weight that is comfortable for you. Do not perform an excessive amount of repetitions as this can cause a real stiff / tight neck the next day.
