How should men and women differ their chest workout to attain a chest suitable for their gender? Here are the qualities that I believe are masculine and feminine. Your thoughts may differ, but I'd like to hear chest exercise variations that attain these particular definitions.
A masculine chest should be like plates of armor. They should be wide, flat, and square shape, They should not be bulbous. The top should be like a plateau and not recede smoothly into the collarbone. It should not be top nor bottom heavy, but rather even throughout. Dexter Jackson, below, is a great example.
Lex Luger, below, shows an example of a feminine male chest. His chest is round, soft, and squishy looking. We would call these "man boobs" if he were fatter.
A feminine chest is hard to describe because it is covered by breasts. There should not be a division between the chest and the breast. The two parts should seamlessly join. The chest should enhance the breast, making them appear bigger. Silvana Silvati, below, is a great example.
Below is the total opposite of a feminine chest. The skin around the breast is too tight. You can clearly see that the breast is forming a bulb over the chest. On some more extreme female bodybuilders, the breasts appear to be dried up like raisins.
