I have a weird problem that i suppose nobody else has.
When i do regular elbows out dumbbell chest presses, next day my left pec is always more sore than right. i filmed myself from every possible angle and my form is really good. slow controlled negative, good stretch etc.
when i couldnt solve this problem, i switched to neutral grip elbows close to body dumbbell chest presses and no more uneven soreness.
but now my problem is im not sure if this elbow position hits the chest as much as elbows out grip.
any opinions would be great since most of you are quite experienced lifters.
