Always stand your ground with a bully even if you loose. Stand up again. Bullies are cowards. They look for victims who cow down to them. Bullying doesn't end when you get out of school. It continues when you get a job and your boss pushes you with verbal abuse. Governments and police can be bullies also, but they are called by a different name. Tyrants or "police-brutality" but its all the same thing...... bullying. Bullies want RESPECT. There are 2 flavors of respect: FEAR and ADMIRATION. A person in a position of strength and power should be admired not feared. If you are afraid of someone..... Boss.... teacher.... cop.... coworker..... neighbor.... Now you know what is really going on... bullying. In your own life.... you know this kind of behavior is wrong, so strive to never do that kind of abuse to other people in your life.
Helmets? Lol they're called head guards, but yes backyard boxing will toughen you up. You'll improve a minimum amount over time if u don't have someone to guide you so you should join a gym. Just go visit your nearest 1 and don't worry about getting fit for it - just training is good enough for the mean time unless you want to spar or fight. Then it would be wise to do roadwork
Backyard boxing on the weekends with your friends? Just get the 2 pairs of gloves and 2 helmits.
Find a boxing gym and start going
First of all, how should i prepare? What training should i do to be physically fit for it, and where should i find out how to learn how to box? Is there like a store or something where you pay a trainer to teach you? And i would really love to learn boxing as a sport, also to take care of my bully if necessary.
