Why rating A
Stable fly with constant tension, easy to load.
Mitta rates every exercise from S to C, based on research where it exists and on how the exercise loads the muscle. When Mitta builds your plan it picks from S, A and B exercises and prefers ones that load the muscle at long length. C exercises are never picked automatically, but you can still choose them yourself.
Alternatives
These train the same muscle. Use one if you lack the equipment, if this exercise does not feel right, or for some variety.
