I’ve been doing farmers walks with dumbbells or farmers walks handles instead of shrugs lately. Shrugs have always messed up my neck, even with careful form.
I like single arm shrugs, but farmers walks seem like a better use of my time. I recently bought farmers walks handles which I love. And you can load up the 45lb plates on these handles. They’re very heavy duty. Turning the trap bar longitudinally for farmers walks is challenging as well.
I’ll do low-mid trap work from time to time. I think it’s fine to do here and there, but I don’t think you should be spending big chunks of your workout focusing on the trap raises with light weights.
