I'm chuffed the thread's running as long as it is! Am quite sure a wee PF section on MN would be useful, but, then, I'm not exactly objective .
Day - yep, many people find their symmptoms change during their menstrual cycle. Oestrogen/progesterone swinging around changes the elasticity of your ligaments and tendons, so, your pf sags down ever so slightly. Agree, avoid jumping if you can, stepping would be better? Got stairs at home?
Mink - have a shiny, the wee heavy aquaflex is darn near Ninja Level of Fanjo Fu.
Milly - good point. Pilates done well can be brilliant for prolapse. Really good - infact, there's a USA medic who has a DVD of pfilates, pf pilates www.pfilates.com/. It's good, evidence based exercise (he, erm, got a bunch of women to do pilates with a sensor up their snatch to measure the forces created and designed the exercises round the results.) The music's a bit annoying (to me) but, it is good.
the problem with pilates is that if you are not strong enough to hold the pose you'll cheat. And, that's usually breath holding and poor posture,which can be enough to pop a prolapse out - same issue as with rowing machines.
so, if you've got a great teacher or trainer, go for it. If you've got a busy class and aren't really getting much attention from the leader, be careful, doing them on your own with a video - be really careful. As with any exercise, stop if you've got pain.
