Yes, you can learn boxing by yourself, but it is essential to understand the importance of safety measures while practicing without a coach or trainer. Boxing is a physically demanding and high-impact sport, so you need to take precautions to prevent injuries. It's crucial to properly wrap your hands, wear the correct gear, and learn the correct technique to avoid unnecessary injuries. Warm-up and cool-down exercises are also a must to prevent muscle strains. And most importantly, don't try to rush your progress - it's better to slowly and steadily improve your skills while ensuring your safety.
