Set the pulleys at the lowest level of the cable machine and position an incline bench in the middle of the stand. The bench should be angled upward at roughly 45 degrees.
Grab a pulley in each hand and lay down on the bench. With a slight bend in your elbows, extend them to your sides to that your upper arms are parallel to the floor.
With your feet, butt and shoulders firmly planted and hands facing in, press the cables upward in a circular arching motion until you feel a strong contraction in your pecs.
Lower the cables back down following the same path until your upper arms are parallel to the floor, and repeat.
