How do you practice writing?

I’ve been skimming the internet and have only found ways to practice business writing, professional writing, and other forms that I’m not really looking for. So many writers and authors talk about writing every day. That makes sense if you’re working on a novel or writing a story, but what if you’re in between stories and don’t really have ideas for a new one? How do you continue to practice your writing if you don’t have a story to work on. What do you do to practice? Leave your comments below!
