I know in the UK, they do not allow punches to the head, even standing, on an amateur level. So that takes away a lot of what you can do with your boxing unless you're one of those Henry Armstrong types.
Get a strong background in grappling- Brazilian Jiujitsu, Judo, or even Catch wrestling or Luta Livre if you can find it. Those will provide you with the skills than will translate better in an amateur competition.
Since kicks and knee strikes are allowed under the amateur rules (at least to the legs and body), it wouldn't hurt to pick up some Muay Thai as well.
Training in these systems will likely introduce you to someone who can hook you up with an amateur fight- not truly a tournament format (fighting multiple times in one night sucks, not sure they even allow it under the amateur rules over there) but a one-off fight. If you can search online for local MMA gyms, that will help. If you can find the results of local competitions in your area, then trace the fighters back to their gyms (often it's listed in the results), you can fight gyms with a good track record.
I have to say for someone who says he enjoys this form of sport, I'm a little surprised you don't know more about it. I don't mean that as a criticism, I'm just wondering where your information (or lack of it) is coming from. It may be forming an image of MMA in your head that's different from the reality of it.
Lets not call it cage fighting and call it mixed martial arts instead. This should be fairly easy to find a gym that does this, but i would recommend doing something like boxing before you start. you want to develop some sort of overall fighting style which you can build other martial arts around, instead of just jumping in there and going for it
um your a crazy person if your willing to just jump into a amateur fight i assure you youll get beat up real bad. you NEED to train for a while first. but ya if your worried about brain damage and dont like hitting people in the face i suggest you just do bjj and compete in bjj
Get a ticket for wwe hell in a cell next sunday.. sit in the crowd.. on any cell match run to the cell force yourelf in and beat up the wresterls (i would recommend going for paul heyman, he's a *****).... then you will be taken seriously when you show the world how tough you are. good luck
Silly boy, you won't get brain damage from a decent blow to the face. It'd take a metal chair or a baseball bat at full force to the face for that to happen.
I also wouldn't encourage you to go to a cage fight, it will hurt... If you're looking for money then go work at a place and get paid without killing yourself. If you're nuts about it then sure, why not? I can't stop you.
Basically im 16 (soon to turn 17) i am not the stereotypical person you would expect to want to join cage fighting usually its brawny lads who enioy sports which not not me, im a high acheiving a level student. Im small but can take a punch and give one when it comes to it. I want to enter into some form of amateur league. I understand that cage fighting for someone like me sounds stupid. But i can fight and have done in the past. How would i go about entering a tournament? Do i need to proffesionally train to be allowed to enter or is that just a recomendation and what sort of training should i do. So far ive been training in boxing with a trainer. Any advice? Thanks to all who answer and please dont just say dont. I know the risks and i enjoy this form of sport. I intend to join regardless of you saying no.
