Standing with your legs slightly apart. You’re in front of the trap bar on the floor or on a support :

Take the trap bar, paying attention to centering your grip (attention : with heavy weight, a poorly adjusted grip will rock the bar backwards or forwards).

You have your head straight or a little bent forwards and your abs squeezed. Do shoulder shrugs.
This exercise works the upper trapezius which is inserted on the clavicle, the acromion and the scapular spine and which goes up to the superior nuchal line the the skull.
The rhomboid major / minor muscles and levator scapulae muscle work a little bit.
The trap bar created to work trapezius by lifting heavy weights without rubbing against the thighs like dumbbells or barbell.
la barbell.
Note
People with long clavicles will always have more difficulty doing shoulder shrugs than people with short clavicles.
