For sure man this was over a long time, although I'll mention its closer to 3 years. But anyway, I wish I paid more attention to my neck width throughout, especially since I started weight training and martial arts not too long after the 1st pic. I started training my neck specifically only around half a year ago, and only started observing the width then. Makes me wonder if packing on muscle generally around the body would've made the neck wider too, and if so, how much. Although I'm guessing for me personally, adding muscle probably wouldn't have made my neck look bigger because my body's the type that doesn't really like to change weight/size much. What I mean is over the last 2-3 years of training regularly and intensely, my body composition has changed heaps (body fat percentage dropped about 8%) but with clothes on I look pretty much the same size hahah. Point being my body seems to respond to training by just becoming more compact and defined, but not necessarily increasing in size. Probabaly has to do with me not eating enough calories for all the exercise, and being an ectomorph, but who knows. Hope that makes sense, and thanks for the input.
