hell yah its a good idea. me and my bro have been beating the shit out of each other for years. but i would recomend buying a punch bag between you and hammering away at that. if your just boxing for fun you would be supprised how much you could teach your self by just trying things out on the bag and watching boxing and takling points that you notice about footwork and turning your wrists and rolling your shoulders etc. there is a lot too it.
