Pelvic floor 'implements' - any good?

[tonton]

I'm pregnant and vaguely considering these - not acutally sure if you can use them while pg or whether I'd have to wait until after. Keen to improve my muscles and not sure my excersies and done that well. Anyone used one?

I know someone who is a pelvic floor physio (really! I hadn't realised it was a speciality!) and I'd wondered about these weights etc.

She said the exercises alone, done properly, are the best. The weights are only really useful if you desperately need more structure and won't just remember to do the exercises.
