Yes contrary to popular belief it's not all about squeezing for dear life there are those ( more than is realised ) that actually have hypertonic PF which can also cause leakage it's not all about laxity where leakage is concerned, you can also have a tight & lax PF at the same time, which can also cause leakage.
I see a women's health physio & I don't need to do PF exercises & many ladies in my group have also been told to stop doing them as they are over tight.
Athletes especially can suffer from bladder issues due to being hypertonic there PF is permanently switched on.
There are more and more articles now on this problem of over tight, also it's about the PF working in harmony so when doing a PF its very important to release & relax it otherwise it gets stuck in a tight state a PF has to work in harmony & to work when called to action but to relax when not needed.
Also so many don't know how to do a PF correctly it's about coordination of the breath & starting at the back passage not a case of just squeezing the vagina with all your might with the incorrect breath as many think is the correct way.
I have been in a lot of groups over the years ( pelvic pain) & the majority have been told to stop doing PF exercises & do reverse kegels.
I have a check up every 3-6 months with my WHPT & my PF works perfectly & that's from doing no PF exercises as the PF exercises where causing me pain.
