Bad function of the pelvic floor muscles (i.e. symptoms above), weak butt, tight adductors and a lot of sprinting and kicking could’ve led to pubic instability/osteitis pubis, right?

But are the pelvic floor muscles actually too weak or could they be too tight like described in this article from katy: https://nutritiousmovement.com/atootightpelvicfloor/

I did a lot of sitting, a lot of heavy lifting and a lot of ab-work the time the symptoms got worse.
Could tight pelvic floor muscles also led to pubic instability, bad bladder control etc. or do they have to be weak?

The treatment would be pretty much the opposite if they are too tight/short, right?
