i have an all out shoulder workout once a week but no matter what i do i can't get them to feel ANY soreness whatsoever.

standing shoulder press (dumbell) - 4x12
side lateral raises (dumbell) 5x10

dont know the exact name of this one
bent over reverse flys (dumbell) 3x10

front lateral raises (dumbell) 4x8
sitting shoulder press (barbell) 3x6


any tips/advice? thank you
