C'est ta morpho !
La science dit ca :
"research has shown that you can't really increase emphasis on the upper or lower pec, all you can do is decrease emphasis. For example, during flat bench, the whole pec is maximally activated. During incline the lower pec is considerably less involved. Other wise you could not lift the weight in the proper plane of motion. In other words, if the low pec contracts while doing incline bench, the bar would pull towards the legs and you would lose control.
In my opinion the best bench angle is a slight incline which puts the sternum parallel to the floor.
The use of testosterone in bodybuilding for the last 40 years has greatly confused the concept of training the chest. Testosterone causes preferential growth of the shoulder girdle (upper chest, traps, shoulders). This growth has been explained in the magazines as due to some special exercise that this or that pro bodybuilder uses. Well, it isn't.
The biggest determinant of the ability to isolate different parts of the same muscle "group" is innervation and the ability to control activation. Usually we use plane of motion to force the body to inactivate whatever part of the muscle group we want to de-emphasize.
Maximally activating the entire muscle group is the best way to growth (according to HST). Let nature determine your shape (because it does), and stop worrying that you don't look like somebody else. Just focus on making "your" physique the best it can be."
Tout ce qu'on peut faire c'est diminuer l'emphase sur une partie, pas l'augmenter, de meme pour les différentes parties du biceps ou triceps etc. Du moment qu'un exercice travaille les différentes fonctions d'un muscle... Mais Bryan fait bien d'insister sur la SHAPE qui peut être totalement différente d'une personne à l'autre (voire les photos des membres).
Pour les pecs, il y a l'example du pote de Pousseur de Fonte !
Autre :
"Sure research shows that activation can be switched to one head 'more' than another. But all this is simply doing is decreasing emphasis on another head, therefore weaking the movement. Furthermore, this has nothing to do with strain, but rather its a neural factor of which muscle is displaying the force."

Comme le disait Jones un exos qui bosse PLUSIEURS fonction en meme temps est aussi bon ou meilleur qu'un exo d'iso. En clair ca sert à rien de faire DI + DC, seul le DC suffit (a condition de bien le faire).
