Preparing for a VBAC Labor

Hi. I am 32 weeks pregnant with my second and my first VBAC. I never labored with my first. She was breech and I had a scheduled c/s. I have NO idea what to expect from labor and delivery. I am anxious about making sure my body is in the best possible condition for labor. I was wondering if anyone had any good exercises, techniques, or resources  about preparing my body for labor? TIA!
