Are there any other exercises I am leaving out? I am 100% that my chest is lagging behind. It annoys me because I have always had large biceps and have significantly increased the mass of my tris/abs/shoulders in the last six months. It just appears while I am trying to isolate my chest I am still putting pressure on my arms to do the work. Is there any other exercises I am missing. I just believe it is difficult to totally isolate my chest- for instance I was doing flyes on a machine and lowered the weight significantly to make sure I squeezed my chest very well. After I do the exercise, my chest if hurting but my biceps are hurting much more. I have watched several videos online about correct form and I am doing it correctly. Very frustrating!
I guess my desire is to leave the gym knowing I destroyed my chest.
You wouldn't want to "destroy" your chest. A lot of guys follow this false notion that for a muscle to grow it must be absolutely be gym raped to the point of failed sets.
I perform only one chest-dominant lift three times a week and my chest has been growing just fine. What's more important than perform set after set is ensuring (if hypertrophy is your goal) you're controlling the weight; what I mean is, you're not trying to just lift the DB of BB up..you need to focus on what muscles are working and how hard each one should be working. I think a lot of guys who simply power through their sets tend to overuse their triceps on the lift because they're pushing primarily with their arms. However, what you need to remember with compounds like bench is that your arms, while assisting with the applicable muscles, is really just the medium by which the weight is moved. Your pecs are the primary muscle in the movement, and you need to focus on that.
"Feeling" your pecs doesn't mean squeezing them on the top of the concentric. All that might do is give you a bit of an extra pump (which is meaningless, anyway...just fun). "Feeling" your pecs would involve focussing on them and what they in conjunction with their assisting muscles are doing.
For instance, for my first year and about two months of lifting I couldn't feel deadlifts in my legs; it felt like a pure back exercise (though it does work the back through isometric tension, it's really a hamstring/glute-dominant lift (just to bring up because I'm so sick of people putting in their back work)). I was also having similar problems with other lifts; I just didn't understand or appreciate that the body's muscles work as a system to control objects and move them in particular planes (e.g. vertical push, etc). What helped me the most was this book I read on bodybuilding psychology. It taught much about what I said before with focussing on the muscles and what they're doing.
It's like what Arnold talked about in Pumping Iron in the famous concentration curl scene ("blood rushing..."). I focussed on my back side as a pulley system, from the calves all the way up to my upper traps. From the bottom of my deadlift concentric I visualized my muscles as a long, tight rope running up my hamstrings from my ankles and up and around my back and to the BB itself. When I began to lift I imagined little workers pulling the ropes near my calves and tightening all the involved muscles to pull the rope downward, lifting my torso upright as the BB now took off from the ground. I also visualized my heart pumping oxygen rich blood to my muscles to support the high-intensity work to ensure that the rope stayed tight and strong.
As it just so happened, I finally fixed by rounded back issues, I moved my deadlift up for 10 reps by over 30 lbs, and after my 3 sets were over my back felt worked but not sore or (most importantly) in pain and my hamstrings and glutes were sore and pumped hard!
Visualization and focus does wonders. If you understand exactly what's going on when you perform a lift it will help you control your muscles and train them exactly as you want to.
Your mind can make things happen.
