Hi im thinking of starting boxing there is a gym in my local area. However i have some nooby questions to ask :P

1- Will i get the shit beaten out of me as im slightly worried about a broken nose but i think i will be able to put up with it (although they are nothing alike i got my front 2 teeth kicked out playing rugby). Will my face be mashed up and ugly XD how much does a broken nose hurt btw?

2- Do i have to compete in tournaments? and what is competing like for example what are the benefits

3- will the training get results as i am looking to gain some lean muscle mass, lose weight and gain confidence and toughen up.
