@ilivebecausehedied I overdid it one time , it got sore but it was almost 3 months later , i was doing twice a week but now doing once a week 3x12 front 5kg plate. Back of head as same but not superseting it anymore.
@raykay i saw jeff nippard neck video , i superset front and back of neck with 2.5kg plate on my head while laying on bench twice a week 15 rep of 3 sets. Its been 12 weeks. It got little bit fuller before it was skinny like a lean person.
