Sorry to say bro there are just some muscles on a natural that will never "pop" like that. It's the cold hard truth. That's why guys use steroids. You can achieve a decent, impressive physique naturally but as a natural there are some things you'll never achieve. Unless you are carrying around a certain amount of fat free mass like a pro or juiced up bodybuilder don't expect to look like them. It's naive and will set you up for disappointment. Obviously the idiots in this thread arguing over what exercise is best are too inexperienced or too stupid to realize this. If you want to look like a juicer you'll have to use drugs like a juice does. Otherwise we'd all be training naturally if we could achieve the same results. 3/4 of the people giving you advice on here have probably never trained on drugs so they don't understand that. Or they have never trained long enough naturally to realize what a real natural can attain without drugs.
I love seeing all these natural guys in the gym doing countless amounts of shrugs thinking they are going to have huge traps one day. In my experience and in my opinion huge, muscular traps are one of the biggest dead giveaways a guy is on the juice. A natural just can't develop his traps like a guy on drugs with the ability to put on more mass can. There is no special exercise to make a muscle "pop". It either gets bigger through hard heavy work or it doesn't. Any idiot that says otherwise is just that. This whole nonsense of bringing up a "lagging" body part is something that steroid using bodybuilders can do. Not naturals. Or atleast not to the same degree. Your muscles just don't grow as fast as a natural.
I had to copy and paste this into Microsoft Word. I've never really heard anyone come out and say it, but I've always believed it.
You watch a juiced bodybuilder "bring up a lagging bodypart" for the next show. What do you really see? What are you really seeing?
We have all seen the genetic freaks who don't even work out. Big huge calves, traps, delts, nice abs-- that's where the first statement rings true "Unless you are carrying around a certain amount of fat free mass"-- but I have never seen a natty truly bring up a lagger. I've even seen heavy juicers bust their asses to try and bring up calves. That rarely even works.
Sad thing is; statements like these can kill the motivation for some hard workin' folks. Sad, but true...
