Give them reasons why boxing is great. take it from me who's been boxing for 6 years and at a gym for 1. Boxing is fun and gives you confidence. I've met many people at my gym who came in shy poindexters and turned into well crafted, and poised individuals. Also you dont start sparring for at least a month usually more depending on skill, and maturity. And you wear headgear that protects the main areas that contribute to knockouts and permanent injury. And your coach will always watch and if necessary intervene. And most gyms if not all respect anybody that just wants to workout and do mitts and not spar. Boxing is a very beneficial sport to get active in and the fact that your parents would make a close minded statement that you'll get hurt is silly. At least check out your local gym and then make a statement

Tell them you will work hard to become pro and when you turn pro youll make a lot of money and then say that you will pay them half of your millons of dollars or you could promise them to get good grades in school and then if you make that deal with them they should put you in boxing or you could just wait until your an adult they cant tell you what to do when your an adult

Ask them to sit down with you and explain this to them. Boxing advantages

Courage

dedication

determination

responsibility

coordination

discipline

and above all a confidence factor that will follow you throughout your everyday life.

Tell them all will be under controlled conditions, with proper technical skills, training and supervised sparring .

If you become pro, I'll meet you in the ring
