A bigger bench means shorter arms! That is to say that if you have shorter arms and a barrel chest you will have a bigger bench which means you will grow your chest even more (arms will stay the same length sorry…:).
I think that most who find great success making their chest larger by benching are blessed in the two above traits. Others, like you and I it seems get larger delts and tris if we bench. We also eventually get shoulder problems, but that’s anothr thread…
There have been many coaches such as Vince Gironda (he turned out champs like Larry Scott, Don Howorth, Bill McArdle etc. Even the great Arnold trained under Vince for a while) who have believed that benching works the pecs in a secondary fashion, unless of course you are blessed with the two traits above. The chest will work when you bench no question, but the delts and tris more so for many of us.
If you want a larger chest change up your rotuine. For example, stop benching and do Dips, wide weighted push-ups, maybe some dumbbell benching with a low stretch, and (Cough) flys! Yes…Flys…There are many (Arnold being only one) who think that Flys build the chest better than any movement. The actual function of the pectoral muscles is to move your arms across the front of your chest. Now let’s see what movement does this? Oh yes FLYS! Do them heavy and deep, try it, what have you got to lose?
Finally, if you want your chest to grow, and it hasn’t grown stop what you are doing! You and I both know that one definition of insanity is doing the same thing over and over again but expecting different results!
Forget what your friends say. Forget the age old question “how much can you bench?” Be a freakin rebel and experiment! This might even mean GASP…not benching for a while. Figure out what works for you! Forget all the clones who will tell you that you have to bench.
If results for you mean trying other ways to work your chest then go for it!
Best To You,
