The best way to exercise chest muscle sewing is barbell bench press, as shown in the figure below.

The exercise parts of the lying dumbbell bird are shown below, and the exercise parts of the oblique dumbbell bird are shown below, mainly exercising the upper part of pectoralis major.

If you train at home, you'd better have a barbell if you want to practice the middle seam of chest muscle. If the grip distance between hands is not fixed, it is difficult to stimulate the middle seam.
