How do you exercise your chest?

Pushups are the #1 best chest exercises. If thei're too easy for you, then try doing them slow, 2 seconds down, 2 seconds up.

Its very important that you hold your torso rigid and straight like a plank, flex your abs to do this. Watch yourself in a mirror or have a buddy watch you, most people make the mistake of sagging as they get tired.

One more thing - bench press setups are just a waste of money, if you really want to get great pecs.

Some great pushup workouts (source: Scoobysworksop.com)

Knee pushups: When starting out, the weight is on your knees and your hands. Put padding under your knees to avoid injury. Do as many as you can with good form.

Basic straight pushups: Body is straight and rigid as a plank.

Ultrawide pushups: For this advanced pushup we take a really wide stance. How wide? Try and put your fists 4-6" further out than your elbows. This pushup is a real challenge although you wont be moving very far up or down (because of the wide stance).

Rolling pushups: They are a combination of pushup and fly. For this exercise you use dumbbells as pushup stands and loosen the collars so they roll. To perform this exercise, you try to keep your arms as straight as possible and squeeze your pecs together which rolls the dumbbells together and moves you to the up position.

Backpack pushups: If you are an advanced bodybuilder and cant get enough of a workout from normal pushups, here is an old idea - backpack pushups. These come in handy too when you are on the road and cant bring any fitness equipment along. The basic idea is to put some heavy weights in a backpack and then do pushups with the weight providing extra resistance.
