Hold a heavy barbell in both hands and with arms straight but not locked, 'shrug' your shoulders repeatedly.

That's what I'd guess anyway.
I presume you mean the trapezius muscle
As well as shrugs, do upright rows
handstand pushups are also the ****

wow, lots of respect if you can pull of a handstand pushup, those things are hard.
If you want a challenge as well learn to clean or snatch a barbell, that works everything as well as seriously pushing the trapezius.
