You cannot separately target the clavicular head. You cannot work the "inner chest". You CANNOT work your lower abs. Hack squats will NOT bring out your sweep. Your muscles are NOT special, they work just like everyone else's. Being loud and condescending does not change the fact that you're wrong. Posting a picture of a muscle without understanding even the most rudimentary facts of biomechanics/physiology does NOT add credence to your argument.
You cannot turn lead into gold. There is no such thing as Santa Claus. You cannot change the world. AND YOU CAN'T BUILD YOUR FUCKING UPPER CHEST!
Thank you. Do a frickin' search for god's sake. This has been argued over and over and over and over. And the argument goes something like this:
Questioner) "How do I build my upper chest?"
Person number 1) "It is physically impossible to build your upper chest. It may be a separate muscle, but the degree of stimulation even during incline movements is the same. The indicators/causes of hypertrophy (fatigue, microtears, hormone/enzyme release, etc.) are identical in both the sternal and clavicular head of the pectoralis major, even during incline movements. Under sufficient stress to elicit an adaptive response, both heads will maximally contract. Chest shape is genetically determined, you cannot change it."
Person number 2) "Do inclines!
Person number 1) "Did you not read what I just said????"
Person number 3) "Yeah, inclines and seated inclien (sic) crossovers"
Person number 1) "You're idiots.
Person number 4 (aka 'meathead guru', claim to fame = three cycles) "Hey person number 1. You're an idiot. I can change my chest shape. Arnold said so."
Person number 1) "I give up"
Persons 2-4) "We win! hahaha. *dance around thread in a vaguely homosexual manner before running off to the gym for "lower lat" day.*
