I can't currently run without leaking (quite a lot).
I do Pilates to try to help my pelvic floor and I bought some weights to tone my pelvic floor (but haven't used them in ages)
I see people I know who've had twins, several children (I have two) all running and enjoying it.
If I took up running would it get better or am I doomed to be piss soaked by then end of every run (I tried tena but found the wetness very disconcerting)
