As high as you can.
Are you saying they should be coming up as high as they do when I fully contract my traps with an empty bar? Or are you just being a smart ass? lol
Probably isn’t a problem, but it won’t be optimal for trap stimulation because it would incorporate more of the biceps doing the work rather than the traps. If contracting the tri’s help you focus more on the main muscle then yes. Squeezing the bar hard should allow you to also squeeze the tri’s as well, making it easier to keep arms straight. [/quote]
Alright. I’ll give it a try keeping my arms straight next time I do shrugs.[/quote]
Something else you might consider doing to get an even more intense contraction of the traps is to drop your head a tiny bit forward and down at the top of the shrug. When I do this, I get a little bit of an extra “squeeze” in them.
