Neck training + jaw area (pictures)

[cvunit]

Is it worth training neck if it causes my under jaw area/hyoid to slightly lower? For example my jaw goes from this

(Clear/tight under jaw) to this after training:

(Notice how it isn’t as tight as the other picture)

That’s my problem. It’s either a pencil neck and very defined jaw or a slightly less defined jaw and a thicker neck. Not sure what to do

Good cope. 90% of jaw width is required. If you have a bad submental region after that then you probably have lack luster forward growth, high bodyfat or a poor submental region.
