Kegel Exercise Massage Balls consist of 2 balls per set, i.e. 30g pink balls and 40g blue balls. It is an apparatus to assist in exercising female pelvic floor muscles and vaginal ring muscles, which is effective in improving female pelvic floor dysfunction. When using the device, after thorough cleaning, you can start with the pink ball once a day for 30 minutes and stick to it for one month. In the second month, you can replace the blue ball with a vaginal ball, or alternate between the blue ball and the pink ball for 30 minutes a day, and when you are comfortable with the control, you can train with both balls. Adjust your training plan according to your situation.
