Does walking really help induce labor?

Janice

I know I should be walking either way but I'm 34 weeks pregnant and work full time so normally am to tired. I want to get my body ready so I go into labor on my own. My dr said if by 39 weeks I'm not dilated at all then I have to do a C section . So was just curious if I start walking 30 minutes a day if that will help move the process along
