As a boxer we get hit in the head for fun. This amazing tool takes the sting right out of a well placed hook by strengthening the neck muscles required to stabilize your head.
You gotta have a strong neck in jits. And this seems to help for sure.
Adapting to the iron neck is like anything else - moderation and some linear programming. I knew my neck was a weak part but didn’t realize how well strengthening would be for eliminating my pain. 100% recommend
I have to be honest, it’s not that comfortable to wear but... after decades of neck pain from fracture injuries, my pain levels have been reduced 90% - the is literally the first time I have ever experienced consistent pain relief from physical therapy. If you have a jacked up neck (like mine). Buy the pro model, use it consistently, it is amazing how much better I feel.
It's a bit awkward at first but with each use it gets better and better. I've been taking it slow adding it in before my strength workouts and am slowly noticing improvements in my neck. I would recommend to anyone looking to build up their neck strength.
