Introduction and general information
Upper chest… This is a really sore subject, as often this part looks lagging behind. I will say even more: not often, but almost always. There are several reasons for this. The first is the most banal: the upper chest is physiologically quite small, and, accordingly, cannot look like the main chest. In other words, this is a small muscle, and it is more difficult to break through a small muscle than a large one. So, for example, the back will always grow faster and add more to the total mass than, say, the shoulders. Although there are individuals, such as Franco Colombo, whose upper body is physiologically quite well developed.
But let’s omit the genetic problems, because if we wanted to be what nature planned for us, we would not think about how to pump up the upper chest, and would not be killed in the gyms. We are changing genetics, becoming stronger, bigger, and outwardly different from ordinary inhabitants. By the way, about the phrase “changing genetics”. This is not a typo. We are really changing it and directing our kind along a more perfect branch of evolution. So, if you have achieved significant hypertrophy of your muscles, with 100% probability, your child will be more prone to hypertrophy than if his dad would not play sports. This also applies to endurance and other “functions”.

And so, let’s get away from genetics and the second reason: insufficient load on the upper chest. Indeed, often the load on the upper part is limited to some bench press on an incline bench, after the main press. I myself am not a supporter of “swotting” the top during the period of raw mass gain, and I do not put such exercises in my training programs. The reason is the same, physiological: the muscle is small, and the priority is in large ones. In addition, the top will still work when doing regular presses. Do not try to pump up your “top” so that you can put a glass of water on it, if in general you are not yet massive enough and your chest does not differ in special volumes. I believe that it is necessary to give a sufficient, isolated load to the upper chest already when you yourself and your chest in particular, are already quite massive.
If so, then there are several ways to pump up the upper chest.

Method one.
Start from the top. That is, when you start training, do the exercises for the top at the beginning, and only then for the main part. That is, at the beginning, say, press on inclined, dumbbell wiring on an inclined, and only then a regular, vertical dumbbell press, etc. Thus, while we are still full of strength and fresh, we can most effectively work out the lagging muscle.

Method two.
Break your chest workout into 2 parts. For example, one week you do the top, the next week you do the bottom. If you are on a program that consists of easy and hard workouts, like here, then the light workout in the second week can be omitted. And you will end up with something like this:
I will give an example on the second cycle.

The first week will look like this:
Bench press 4 to 8;
Dumbbell bench press 3 to 8;
Breeding dumbbell lying 3 to 8;
French bench press bench press 3 to 8;
Dumbbell press from behind the head 3 to 8.

The second week will look like this:
Incline bench press (head up)
Incline Dumbbell Press
Breeding dumbbell lying, on an inclined
Next, triceps, the same as in the first week.
The number of repetitions is the same.
