Trapezius is a muscle?

Alright so lets begin with talking about what traps are.  The trapezius also known as traps are the upper part of your body connecting your shoulders to your neck. To work out this muscle you must elevate your shoulders. So lets get to the workouts. When you go to the gym you always wanna have like a 5-10 minute warm-up with a jog on the treadmill or by doing some jump ropes. Stretch the muscle(s) that you're going to work out . So the first exercise to do is go to a flat bar put your preferable weight then pick up the bar and lift it straight up and down. The motion is like when you make the body gesture of shruging when a teacher ask you a question you dont know. Do 3 sets of 10 reps meaning 10 times up and down in a row then take a 30 second break and that 3 times. Then move on to your next work out, grab 2 weights one for each hand once again with whatever weight you feel comfortable with. Shrug 10 times up and down, shrug 10 times while rotating shoulders foward, and then shrug 10 times while rotating shoulders backwards; all this is one set, do 3 sets of these. While you're doing this your traps should be feeling the burn! if not on your next sets of whichever workout you're doing you should do more weight. This concludes the only trap workouts that I do if you have any trap workouts that you know of that work please comment and tell me.
