Tell Me About Boxing

[blackjack]

I was thinking of getting into boxing and I would like to get into it, I am 16 years old 190 pounds, 5' 8", a little muscular but would like to gain more and lose some fat in the process. My mother is a little worried but I would like some more information about it to convince and and also I was wondering if it would be a good idea, thanks. EDIT: I also have very broad shoulders, and a muscular upper body
