Ok read most of the post here...
Im a personal trainer, and working at competing in my first amature bb show this year.
Many of you support, both push pull/opposing muscle group ideas as well as brun outs
Bottom line is yes you have to work every group of muscles to build them propotionally. Yes you do use calfs to stabilize while doing standing dumbbell shoulder press but that doesnt mean you dont work calfs..
the guy is an idiot. And i do admit to using "juice" but only to push past natural limits of muscle growth and development, but dont let that base you judgement or opinion on me.
I do know what I am talking about here.. I train 4 people on a reg basis. To properly train muscles and build strength you must focus 3-4 exercises per major muscle group to achieve growth in that area.
