Walking

So I’ve heard from many different people that walking and staying active will make labor easier!

My job is pretty much me sitting all day, I do get up ad walk around but there’s only so much I can do in a small office & im there 6 days a week 😪

After work about 3-4 days out the week, my husband and I go on 2-3 mile walks. Is this enough or should I be doing more?

& can anyone confirm that walking/ being active makes labour easier? Or does this just depend on the person?
