For life of me I can't figure out why my dominant pec is slacking behinde left one which is pumped much more. Seems like right front delt takes all load.

I tried doing it with retracted scapulae and depressed but it makes right humeral joint hurt often when i unload that arm, when i let upper back move freely sometimes it doesn't hurt at all or doesn't hurt in certain paths of ROM I can't figure out.

I use that outward palm rotation when pulling up. Arms are 45° flex, i warm up with some rotator cuff exercises.

Any suggestions, i don't want screw up my arm continuing expecting it will even out.
