Personally I never really decided to, I just really really wanted to and my parents never met me so I self taught myself for a few years. I barely had any padding and it was on hardwood floor, definitely not safe, but I started going to a gym and it got better! My best tips if you know you’re safe are to make sure you have lots of mats and padding, find all tutorials you can online, make sure to condition and stretch, and record yourself! It might seem weird but definitely set up your phone or something in a distant area and rewatch the videos so you can make any and all corrections necessary. It will help rid of any bad habits and ensure good form! Also, be sure to learn lots about the sport. There’s a lot of terminology and different things that would be good to know. I learned this all from online though, so you should be fine. Wishing you best of luck!
