Inducing Labor

I'm 34 weeks, and I'm looking for ways to help the labor process along for when it's time. What specific things seemed to help your labor progress or speed up the process? I know it all depends on when your body is ready, that's why I'm looking for ways to help prepare my body for labor. I'm slowly starting walking more but don't want to push walking until I'm atleast 36 weeks. I am not looking for ideas that put me at risk such as Castro oil, etc. thank you in advance for your suggestions ladies. (:
