Any opinions on that as a theory?
    Changing the "shape" of a muscle, where bodybuilding is concerned, and the size of the muscle are two different things. The only things that can affect the way a muscle is presented is it's size, the level of bodyfat covering it, the surrounding muscles and posture. I only say that last one because if somebody has postural issues like kyphosis the effect of say a rear lat spread can be affected.

    As for relative hypertophy differences between the two grips, I honestly don't know. The guy who wrote one of the above articles did show that a Wide Grip Pullup with a 45lb plate had a better Lat response than a 90lb chin up. But activation and hypertrophy aren't necessarily correlative.

    Yeah I agree that's why I say emphasise or target. Not isolate.

    The Contreras article uses 135 and 225 for both the incline and flat barbell bench to compare the EMG results from the two movements. Then even with the heaviest incline using 245lb (against 275lb for flat) it still produced greater Mean and Peak results for the Upper and Mid Pec.

    Wouldn't there be a significant difference between claims of targeting the "upper chest" and claims of targeting the "lower chest", considering that the upper pecs are actually a real, separate thing (the Clavicular head of the Pectoralis Major) whereas the "lower pecs"... aren't?

    Pectoralis Major (Clavicular Head)
    I'm sure you know there is antother head beneath (lower than) the clavicular head right?

    Pectoralis Major (Sternal Head)

    Anything wrong with my form here?

    [ame=http://www.youtube.com/watch?v=rP8MIyYxjgY]129kg total x 5 - YouTube[/ame]

    Hurt my left shoulder again doing it the way I do there. I found on another set that the pain decreased if I didn't quite pull my shoulders to the bar and only my chin. But that was sort of a half rep.

    I do palms towards me chin ups cause palms away screw with my left elbow (a lot of pain). And yes, that is an expensive weights belt...
    1rms: BP: 140kg touch'n go, MP: 85kg, Weighted Chin ups:60kg+104kg bodyweight. Squats/deadlifts: Injured, maybe 20kg each now (including bar weight).
