Best Chest Exercises

Bench Press

Works the overall mass of the chest. With your back flat on the bench,
grip the barbell with palms facing up and about 8-12 inches wider
than shoulder-width. Lift the barbell off the rack to the starting
position, which is straight above your face, your arms extended fully.
Slowly lower the barbell until it touches the lower edge of your chest.
Your elbows should be pointed out while the rest of your body remains
in position. Slowly raise (push) the barbell to the starting position
while flexing (squeezing together) your chest.

Incline Dumbbell Press

This builds muscle mass in the upper chest. Using dumbbells allows an
extra 15° of movement at the top than you'd get with a barbell. The
steeper the incline, the more the deltoids, rather than the pecs, are
performing the lift. Too many bodybuilders use a 45° incline. This
is too much. 30° to 35° is perfect for upper pec development.

Peck Deck

Works the central pec with an emphasis on the inner area, building
depth between the pectorals (cleavage). I prefer to do this with
arms straight in front rather than the forearms angled upward. This
takes stress off the shoulder joints. These are better than flat
bench dumbbell flyes. Since dumbbells rely on the pull of gravity,
tension decreases at the top the movement. This is precisely where
you want the most resistance to carve that inner pec detail. If
your pec machine is under repair, substitute flyes between the
low cross-pulleys on a low bench.

Decline Dumbbell Flyes

since you worked the inner pecs with the last exercise, the
decline fly works the outer pec as well as outlining the lower
pecs. Use a 35° decline bench and do the exercise with arms
slightly unlocked. Start with palms up. Keep this hand position
throughout the exercise.
