Major Muscles and Actions Involved
Variant 1: Incline press
The muscles and actions involved in this exercise are a cross between the bench press and the overhead press. In essence, the movement is diagonal flexion, which uses some of the muscles that are involved in the bench press and the overhead press. Thus, rather than describing these muscles and actions again, just remember that the greater the incline, the closer the exercise approaches the muscles and actions in the overhead press, and the lower the incline, the more the exercise approaches the muscles and actions in the bench press.
Variant 2: Decline press
The same concept applies here. In the decline press you do diagonal extension, which is made up of a combination of the bench press and the dip.
The sports uses are the same as for the bench press and the overhead press. Note also that the incline press is most important in the shot put, discus, and hammer throw, as it more closely duplicates the specific actions in these sports.
For the decline press, the sports uses are the same as for the dip and the bench press. The decline press is very important in downward pushing actions, which are used in football, swimming (especially the back stroke), water polo, synchronized swimming, flying rings, and basketball. The movements of the incline and decline presses are used in bodybuilding for full development of the pectoralis major.
