I really wanted to try a barbell style kegel exerciser and I have to say I was impressed. This is a very small and easy to insert bar but it packs a lot of heft. The instructions are easy to follow and explain why you'd want to use a vaginal muscle trainer. I think this type of exerciser is better than the vaginal balls for those who really want to put in the effort and get good results. Even with just casual use you will eventually see results.
