I also want to recommend going to see a pelvic floor specialist physio. I went to a normal physio at the women's doctor and she wasn't anywhere near as good as the specialist I went to later.
There is also a book called womens waterworks which goes through the excercises really well, you might be able to get it at the library.
From memory, the physio I saw said 15mins exercise routine each day. With fast and slow squeezes, and lift squeeze and holds. Also using a pelvic floor exerciser which gives you resistance.
Good luck. I have gotten really lazy with mine and am just getting back into it.
