Singel Arm Cable Fly
One of the essential functions of the chest is to retract the arms, adduction, which is what this exercise does. Running flyes with cable compared to dumbbells has its advantages. You will always have tension in the chest compared to a dumbbell fly where the top position does not load the muscle as much. You can also pull your hand past the center of the chest, which will compress the inner middle part of your chest a little extra, whereas, in a dumbbell fly, they must stay in a vertical position. Like all cable exercises, this one is also suitable for drop sets because you can quickly lose some weight.
