how to build muscle in every part of the chest

here are three useful exercises to build a nice round full looking chest as these three different types of exercises although very similar hit three different parts of the chest.

1: decline bench press:the decline activates uses less muscle fibers from the upper part of the chest. decline works the sternal pectoral muscles,(lower chest muscles).

2: incline bench press:the incline activity works the upper chest and also working the anterior deltoids (shoulders) tearing down the upper pectoral muscles fibers(upper chest muscles).

3: standard bench press:the standard press works every part of the pectorial muscle (chest muscle).
