Heh heh. I'm just someone the new guys who read studies without actually processing the information can hate on for my anti-mis-information taste. But it's the veterans like you that really bring this place some personality. Keep up the good work by all means.
To contribute to the thread though, I have been under the impression that dumbbell presses are best done on incline or decline. I'm not a fan of swiss balls only because to me they represent every doof who thinks they're a trainer, lol, but I can see how the unsteady surface contributes. But do you think incline and declines would be optimal for these specific types of presses, as well as isolating parts of the pecs by turning inward/outward at various points in the lift?
