Labor tips

I am only 30 weeks but just trying to figure out how I am going to push a baby out of me when the time comes LOL. I am going to be a first time mom, and I am trying to do stretches to help and then going for walks each week but just wanted to see if anyone has any tips for like pushing and stuff.

I plan on getting the epidural but just wanted to see if any one has any tips for when it is time to push
