Unless you are a competitive bodybuilder the 'flow' of the physique IMO is not important.
If you are just a gym rat who trains for fun etc do not hold back on your strengths at all work on them just as hard as anything else - that is my view on things. Plus if natural it is not as if anything will ever drastically overpower anything!
Im natural and a but i have body parts that grow super fast.... and yes i strive to be balanced
no one can speak for all naturals and make a blanket statement you will never see a natural with an overpowering body part.. well you can but it wont be correct.... that's what separates a good physique from some who is just big or workouts.. im sure you have body parts you want to bring up? same as anyone else.... natural or otherwise
im sure if i scrutinized your physique or anyone's ...for that matter i could pick out body parts that overpower.... same as if mine was scrutinized...
we all have strengths and weaknesses
