Actually LK, what I was getting at was that I use to do those types of neck specific excercises.
My neck has grown much better from simple big lifts. The day after heavy deads my neck feels like I was in the ring the previous day. Even when I go really heavy on silly things like curls, I strain my neck a lot.
But, if you wanted to learn more direct neck stuff, do a search for neck, neck bridges, etc...I know there has been threads on it. If you can't find anything pm me
