Whether you are doing it for fun or have professional aspirations, you can learn boxing by yourself and master it with time. You only need to learn the basics, get the necessary equipment, know and understand the rules, and overcome the challenges of self-training. It is possible to self-train in boxing, but it takes dedication and effort. If you are serious about boxing, you will need to put in the time and effort to learn the techniques and workouts. There are many boxing websites and books that can help you get started, but the best way to learn is by actually getting in the boxing ring and sparring with other boxers.
