The article never claimed that the decline was better than the incline. They said that studies suggested more muscle fibers were recruited on decline rather than on the flat bench.

i was under the impression the pectoralis minor was mostly a respiratory muscle, this is feedback i got from a video.

Do both. Problem solved.

Metallica, You got that from the "Built By Science" videos; but it's still a muscle, and it contributes to size. Just like developing your soleus pushes your gastrocnemius out, giving you more overall size, so does your pec minor push out your pec major, giving you better size. In fact, I've never heard or read that the pec minor is mainly for respiration, except in the aforementioned program, which is really weak (sorry, but all that program does is feature an out-of-shape "trainer" with a presentation on the names of muscles and the origin and insertion of each.)

I get a better pump and squeeze from doing declines personally. If the goal is to build that upper chest to look like a bulging shelf, then of course inclines are ideal. I try to include flat, incline, decline, and some type of fly in each of my workouts.
