yeah need to be careful with the neck, thats why i dont recommend bridges and the stuff wrestlers do to beginners.
someone just starting out resistance from a partner with his hands will be enough or use a towel
i do believe it's a good thing to train though, if you take a punch it's the neck, if you get whiplash in a car accident good to have a strong neck etc
cons might be you'll have harder time getting a shirt to fit
