Labor exercises & videos?

Me

I took a birthing class with one first and then never labored (breech c-section). We’re due with our second in August and I’m trying for a VBAC. My husband and I remember some of the class, mostly some of the pain management techniques. But I’d like to do some preparation leading up to labor as well.

What exercises or videos or websites do you recommend for labor preparation? I do go for 30 min walks 4-5 times per week, but I’m not sure that’s enough. When I asked my provider, she were really generic (“practice coping skills”).

Thanks for your help!
