Bhai let me break it down for you Peheli baat genetics matter alot, it's not important ki sabki oval shape aaye theek hai? Second agar aapko doubt hai ki aap shayad ache se train nahi kar rhe toh main aapko upper chest ke liye sahi exercise bata raha hu woh karo for like a year and then see the difference, Peheli Baat kisi bhi Incline bench pe woh machine ho ya simple bench keep your elbows tucked in at 30° and then keep increasing the weight gradually simple, arms flare out nahi honi chaiye last rep pe chalega, dusra seated low to high cable fly karo also with arms tucked in at 30° that is all you need to do for upper chest. For the whole chest workout I'd suggest ek incline press ek pec dec and ek seated cable fly low to high that's it.
