While you are busy pumping up your upper chest muscles as well as your lower chest muscles, perhaps you might be overlooking one group of muscles that's just as important.
The pecs (short for pectorals) are the muscles that give the chest its distinct look.
You can't build up the top and bottom while completely neglecting the inner part.
If you are aiming for that chiseled torso, then you have got to show your inner pecs some lovin'.
Here's a couple of exercises for an inner chest workout you can easily do.
Dumbbell flyes are those huge, sweeping motions that start with your arms outstretched on both sides while you are either lying flat on the floor, or on an inclined or declined bench.
They then proceed with your arms being raised to meet each other in front of you.
Hold this position for a second, feeling your pecs contract, then lower the dumbbells again.
Count that as one rep.
Do three to four sets of 8-10 reps.
A close grip bench press is similar to the usual bench press, only with this exercise, you grip the middle of the bar and your hands are actually right next to each other rather than spread apart.
As with the dumbbell flyes, do three to four sets of 8-10 reps also.
Later on you may want to improvise by combining different kinds of positions using either the floor or the bench, or you could put them all together to make one big superset.
