Um...
Pectoralis has two heads, sternal (lower, biggest part) and clavicular (upper part, maybe 1/4 of the chest). At least that's what every anatomy book I have access to says. Now, I hear advice on how to hit a particular head of biceps, delts, and even one of the quads, so why not the chest? Yeah, it's one muscle (like the biceps), but it has two insertions, and therefore it should be possible to preferentially target one over the other. No?
Now, I don't know about anyone else, but I am able to isolate that head. Use a cable machine, pulleys at shoulder joint height. You stand in front of the machine, arms outstretched so that your hands are at eye to forehead level and would be directly between the pulleys when you 'clap'. *Not* a cable flye, more like clapping against resistance. I call them monkey claps because when I do them I feel like I must look like one of those wind-up monkeys with the cymbals (although the cymbals would be higher). I've described the exercise elsewhere in these forums.
Here's a pic showing good definition between the two heads:
The trick to targeting that particular head is having the arms above the shoulders, and pulling together and slightly upwards. If the arms are in front of the chest or pulling downwards, the sternal head is used, so keep the arms straight with hands at forehead level, and the pulleys slightly below so the angle of the cables is perhaps 10 degrees.
Gaz, Merk... is there something wrong with my anatomy books? My definition of 'upper chest'? Innervation of that head and the ability to isolate it? Is my body just 'weird', like I can wiggle my ears and some people can't and everyone who can't is saying there is no 'ear-wiggling' muscle?
