The bench press has two phases: eccentric and concentric. The first phase, as you lower weight toward your chest, is called the eccentric, or muscle-lengthening motion. The second phase, as you raise the weight back up, is called the concentric, or muscle-shortening phase. It is during the concentric phase that you can feel your chest getting tight. Learning which muscles are used during the concentric phase of the bench press is beneficial for focusing your mind on the correct area and therefore improving your exercise technique.The primary concentric mover of the bench press is the pectoralis major, which you may better know as the chest. Depending on which version of the bench press you are doing, you will be recruiting a specific part of the muscle group. The regular bench press on a flat surface mainly works your middle pecs. The incline and decline versions mainly work your upper and lower pecs, respectively.
The Maxicam Standing Incline Bench targets area such as middle and upper pectoral muscles and front deltoids.
The muscles that are affected by this work out are mainly your pectorals and deltoids, but also to a less degree, forearms and triceps. This exercise also helps with your latimus dorsi (lats). There are also back muscles involved that will be strengthened.
Flys work the pectoral muscles of the chest. Usually they are done on a flat bench or an incline bench.
It's kind of a cross between the bench press and shoulder press. It works the clavicular head of the pectorals harder than the bench press. But it is really just an assistance exercise to the two mentioned.
Incline targets the clavicular head of the pectoralis, although you really can't isolate any part of the pecs. It does do anterior deltoid a little more, but that's not the best way to build those. It's really just a secondary exercise to the bench and the press.
Yes, this bench can change from incline, to flat to decline.
upper pectorals, deltoids, and triceps. Because it is on an incline, rather than flat, it's more of a shoulder exercise (& upper pecs). Decline bench press, on the other hand, targets the lowe pecs. It's good to do for added definition of your chest muscles.

No, unfortunately this incline and decline bench cannot be folded.
a 14 year old boy shouldn't workout too much as his muscles are still forming and growing. Exercises that will help to enlarge the pecks are barbell bench press, incline barbell bench press, decline barbell bench press, and decline dumbbell bench press.
