Second: stick to fitness, you must find a good starting point, and someone must take you to practice in the early stage, or a good tutorial or a good coach. This is possible. If you practice blindly from the beginning, you will hurt yourself. You might as well not practice. And it's not easy for you to persist.
Third: if you want to persist, you must not practice too much at first. I suggest you should do it step by step. Moreover, if you have a group of long-term practice partners, you should practice with them. People are lazy. If you set a high difficulty at the beginning, it is easy to give up. Besides, unless you have strong self-discipline, you are easily influenced by the outside world. At this time, I suggest that you can have a group of like-minded friends to accompany you. When you form a habit, your body also forms a habit. Naturally, you will exercise for a long time.
In fact, if you can persist, you will find yourself with many surprises, so don't just ask others, take action on your own.
