Purpose:  To create a wider chest.

Execution: Take a pair of round dumbbell. Get into the push-up position with the two dumbbells in your hands, shoulder width apart, facing one another. Slowly roll the dumbbells apart, stretching out the entire chest. Go as far a part as you are comfortable and slowly bring the dumbbells back together, squeezing the chest. As you fatigue you can decrease the range of motion and get a few extra reps.
