Wanna learn how to shrug? First, let's go over what shrugging is NOT:
Anything under 4 plates on a side. Shrugging with 315 is not shrugging- it's some form of odd public masturbation.
Anything wherein your goal is reps, rather than weight. No one gives a fuck that you did 43 reps with 225. You're a fucking pussy. Go join a Bally's and buy all of your workout gear at International Male.
A movement wherein you ROLL YOUR FUCKING SHOULDERS. Sweet mother of fuck, why in the hell would you do this? Complete development? Yeah. Sure. My cock has better development, and my infraspinatus is still intact. You're a pussy if you roll your shoulders.
So, what IS shrugging?
Heavy ass weight. I work up to 10 plates on a side regularly for singles. I've got surgery for my 60% tear in my tricep and my halved bone spur on Tuesday, and yet I did 15 sets of 3 with 7 plates on a side today. That's fucking shrugging.
No reps over 5. If you're doing more than 5 reps, you're doing the wrong fucking exercise. Add weight, or refer to #2 in the preceding section.
Brutal, painful, and soul-crushing. It should not be something you can do while holding a conversation about Brangelina's newest addition to their brown baby collection.
