What can I do at home to get good for MT practice?

I’m planning on joining in a few months or soon and I wanna know if I can do any exercises or kicking or anything I can do in my bedroom or a open area alone to improve or be more used to it on my first day of practice. I have no prior experience at all but yeah 🥲 I’m a minor so idk if that makes a difference of what I should do bc the practice difference but pls lmk! I wanna try to improve before I actually do practice.
