I got an alert to this thread - my fanjo spies are everywhere on MN...
So, the reason that running/double leg lifts/planks is not great for us with fallen undercarriages is that the pressure on the pelvic floor can be damaging.
Anything that raises your intra-abdominal pressure pushes down on your pelvic floor, and the forces can be really high. Running has x3 your bodyweight in impact force rattling up your leg into your pf with every step.
So, if you weigh 10 stones then that's 30 stones of pressure with every step. Running 2.5miles x2 week is about 10,000 steps - so, no wonder female runners pish themselves.
I do understand, though, that runners want to run. Well, I don't understand it myself, I loathe running with a passion and use my knackered nethers as an excuse to avoid it. But, you can get an endorphin buzz from other exercise - it's just getting good enough at the new activity so that you get the "hit". Hard to motivate yourself, I know. I'd suggest googling "prolapse images" for motivation if I didn't think it'd freak everyone out.
There is the option of using a pessary to support your pf as you run, but, TBH, I'm not that keen. They do work, and can be a great solution for some people, but, if your sweet chariot is swinging low, well, you should probably avoid the activities that are going to stress it further. Certainly until you've sorted the problem - after that a graded return to impact sport, being careful to monitor any symptoms, and using a pessary for support, well, that's fair enough.
1:3 women wet themselves, and physio has an 80% cure rate for stress incontinence. So, it's ludicrous that we're not properly educated on this stuff. I'm on a mission to change that, getting there, slowly.

Swimming is amazing exercise, and very under-rated. I've gone back to it and am in the midst of lessons, now tumble-turning and butterflying like someone who knows what she's doing. Well, some of the time.
There's a new online tool full of advice, training schedules and coaching tips that might be helpful - www.swimming.org/swimfit. They've got a clever googlemap tool so you can chart your swim - I'm currently swimming along at Greenwich. There I am, waving, not drowning.
Am really heartened to read about so many women looking after their pelvic floors. Thanks for the thread
