Fact: Some people use vaginal exercisers/vaginal cones/vaginal weights. These were popular a few years ago when we were first becoming aware of our pelvic floor muscles. But we now know much more about the PF muscles and the best way of exercising them. Like all muscles PF muscles need to be warmed up before strength training and stretched afterwards. When you use weights or other instruments you miss these important steps. You can end up with shortened and tight pelvic floor muscles that lacking nerve and blood flow.
