Contrary to popular belief, the "show me" muscles of the chest -- the pectoralis major and minor -- aren't actually that big. Despite their somewhat diminutive size, some people insist on spending several days a week dedicating set after set and exercise after exercise to developing the kind of barrel-sized chest that's best suited for a 1940s sailor. Sure, it looks impressive, but really, it's not necessary.
Don't get me wrong. Working your chest is important. Your pecs are required for pushing and pressing, and because they play a role in arm movement, you're pretty much using them all day long. Ignoring them completely is a good way to develop muscle imbalances that open yourself to injuries. But you don't need to spend a ton of time training them. To enhance your strength and size, all you need are these four chest exercises. Incorporate them into your workout twice a week, aiming for two sets of eight to 12 reps using the most weight you can handle while maintaining good form.
