The sternocostal head of the pectoralis major is little affected by hand spacing, but is directly affected by trunk inclination. The greater the inclination, the less the activation. There is also a slightly greater activation of this muscle with a wider hand spacing, due, in general, to the fact that with a wider grip, the elbows tend to move away from the midline of the body, which increases the degree of horizontal flexion of the humerus.
The clavicular head of the pectoralis major is affected by both hand spacing as well as trunk inclination. The narrower the grip, the greater the activation, as well as the greater the inclination, the greater the activation. There are several factors for this, including the fact that vertical bar displacement is greatest during an incline press. This is also due to the fact that the clavicular head is involved in horizontal flexion and adduction in addition to pure flexion. The clavicular head will maintain its function as a flexor of the glenohumeral joint until humerus moves above the horizontal position. This is why it is rather inactive when the torso is vertical, as little flexion is occurring.

The Clavicular Head
Now we all know that the incline bench hits the upper pecs. Right? Since the upper pecs seem to help to raise the arm, this would make sense. The incline position would put the arm in more of a flexed position than either the flat or decline positions. According to EMG studies this advice seems to be pretty much true. The Barnett study tells us that the incline position produces just slightly more electrical energy in the upper pecs that either the flat or decline positions. However, the flat bench was found to be very close. While the difference between the two was considered insignificant, the slight advantage of the incline over the flat bench in upper pec activation may be just what some of us need to further develop the upper pecs. "This is all very true," says Robinson. "There is no doubt the incline bench hits the pecs more than the flat bench."
