Chest fly exercises provide greater abduction range of motion and muscle stretch, beneficial for hypertrophy, but stress the anterior capsule and require end-range shoulder mobility.

“Well, I mean, you look at the the amount of abduction that you're getting. So, any press, any dip, any push-up, it's all limited to about this range of motion. But if I can actually open it up even further and get more stretch, we know the benefit hypertrophy wise of of applying stretch to a muscle. But that's a that's an exercise where you are also entertaining end range shoulder mobility and then again excess stress on the anterior capsule.”
