Does training the neck have any purpose other than for combat sports and getting the thick neck look (which I assume is desirable when heavily bulking so your head doesn't look too small?)?
For example, might it help with forward head posture, relieve tightness in the neck or shoulders or be desirable for other common daily activities?
I'm just starting a strength training program that does quite a bit of neck extension work and I'm wondering if I should omit it.
