will exercise help induce labor

My doctor told me that since my baby is huge at 37 weeks that he's pushing for a c section if I don't go into labor by 39 weeks I don't want to do anything crazy like take sum or put a pill up my vag so will exercise help me out I haven't really been active I've been feeling pretty shitty about myself these last 2 months so I think walking or climbing stairs should work right I really don't want a c section it's my first baby I want to experience natural labor  so I'm freaking out!
