Soreness is usually how your body responds to a new stimulus.

What that means is if you have not done X exercise in a while (weeks or months or never) then being sore is how your body responds.

I find once the initial soreness fades, if I keep frequent with that exercise, I'll never get sore again unless I do an insane amount of volume.

Soreness is not your indicator. Strength or size gains are your indicator.
