My upper chest is still underdeveloped compared to the rest of my chest and shoulders, especially when I'm at a low body fat percentage. I also don't seem to be making any progress growing it, even though I tried with decline push-ups and kept adding weight. I'm pretty sure my form is correct as I kept looking it up and trying.

I also read online that chest is hard to develop using bodyweight exercises.

Does anyone else have the same problem? Are there any better exercises or small equipment to hit it better? Tips or suggestions are greatly appreciated.
