It is one of the best Softmaxxes that don't require much effort.

A thicker neck drastically increases your dimorphism and can compensate for a narrow jaw.
It is one of the muscles that are visible when fully clothed in winter.
This way you'll show off your body halo meanwhile the Gymcels are invisible with their Wellensteyn or Canada Goose during winter.
Now you may ask: What is the ideal neck width I should go for?
The neck to bigonial ratio is perfect to determine the ideal width of the neck.
You should train your neck until it reaches a width of atleast 1.1:1 unflexed.
Necks bigger than this aren't worse aesthetically speaking.
Just take a look at this individual:
When flexed it looks wide as fuck.
Same angle:
This is pretty much ideal.
If you aren't training your neck, what the fuck are you doing?
I don't think you want to miss out on this big halo.
Other benefits:
- Being able to take punches. Incel trait who can get knocked out with one headshot.
- Good for martial arts. Wrestlers train their necks all the time with neck bridges and other exercises. Why else you think they have that DOM look?
- Can actually support your body posture.
Risks:
- Sleep apnea is rare. I have no problems at 17inches.
- If you always maintain a good form, you won't experience any neck injuries at all.
- Missing out on having a Mogger neck. Literally the biggest risk. Take the Neckpill.
