i’m gonna add to the slight highjack. Funny a back thread has turned into a chest thread. Anyway, am I reading these statements right? That there is an assumption that incline will not preferentially target the fibers of the pec that are closer to the clavical? (trying to avoid using “upper pec” verbage as I understand that there isn’t “multiple heads”).
It has been my understanding, and experience, that since the fibers do have different angles to them that the effective recruitment of them would be determined by the angle you are pressing. I certainly have felt distinct soreness in only the area just below the clavicle when only performing inclines. It WAS NOT an across the board soreness. If there isn’t anyway to “target” then why wasn’t it across the board? I could say the inverse for a flat/decline press.
If I hold my arm out and up at a 45�??�??�??�?�° angle, contract my pec, and feel the upper portion and the lower portion, the upper portion is contracting harder than the lower. Continuing to hold the contraction, lowering my arm to a downward 45�??�??�??�?�° angle, the inverse is true. The upper portion is looser while the lower portion is harder.
Maybe I’m just an idiot, but I can’t see how this doesn’t mean you can’t preferentially hit a certain area of you pec. Unless this isn’t what anybody is saying and I failed at comprehension.

I agree. I just did inclines a few days ago, and I did not do them the previous session. Upper chest had DOMS after the last session but not the other.
I’ve also noticed a decrease in upper chest mass after not being able to consistently perform incline bench presses.
This shouldn’t be questioned IMO. Incline movements clearly target your upper chest more so than other angles.[/quote]
It’s confusing to read that Dorian claims you can’t target a certain portion and that he feels decline is the best chest builder due to the greatest range of motion (paraphrased from dre1986’s post) when I distinctly remember seeing him rep out 405 on incline in (I believe it was) his Blood and Guts video.
In regards to buzza and his EMG post, just because more TOTAL fibers are recruited in a certain angle doesn’t, IMO, mean that all fibers are being recruited optimally. I just don’t see how you will get any significant recruitment of the upper fibers doing a decline press.[/quote]
I do understand your doubts about targeting just one “part” of the chest,
wanna just point out two things:
- this the link to the university of queensland EMG study on chest (flat/incline/decline bench)
http://www.daveywaveyfitness.com/wp-content/uploads/2010/11/Effects-of-Variations-of-the-Bench-Press-Exercise-on-the-EMG-Activity-of-Five-Shoulder-Muscles.pdf
-about DY doing heavy bb inclines for chest (and his statement that it is NOT possible to recruit just one part of muscle:for example) IF you watch carefully at DY grip (Blood and guts) you see that is a narrower than usuall grip,this could explain something (according to EMG study of U of Q)…
just my thoughts

I think maybe you should read the study again, a little more carefully. Specifically the Results portion. That study reinforces everything I’ve talked about.
From “Results-Clavicular Head of the Pectoralis Major”
“Concerning inclination alone, a significant increase (p<0.05) in activity of the clavicular head of the pectoralis major was evident in the transition from decline to incline press (Figure 3).”
Also, from “Main Effects”
Trunk inclination. The significant reduction in activity of the clavicular head of the pectoralis major during the decline press versus the incline press is due to either a reduction in the flexion component at the shoulder joint or a reduced glenohumeral range of motion."
The hand spacing issue seems to be most relevant to the sternocostal head.
From “Results-Sternocostal Head of Pectoralis Major”:
“With narrow hand spacing, the activity during incline press was less than for the horizontal press (p<0.05). Generally, hand spacing had no effect on muscle activation except during incline press when the wide grip elicited greater activity (p<0.05).”
