Reverse flyes work the back muscles that help open up the chest muscles and lift up the bustline.
Stand in a lunge position -- one foot placed forward and bent at the knee, the other stretching out straight behind -- with medium-weight dumbbells in both hands. Bend forward till your chest is parallel to the floor and let your arms hang straight out downward, towards the floor. Next, raise both arms till your hands are in line with the shoulder, squeezing your shoulder blades. Slowly lower again to the start position. The movement is similar to a bird flapping its wings, but much slower.
Do 12-16 repetitions, rest and repeat.
