Granted the odds that you will make it to the big leagues with no kind of martial arts background and starting at age 20 are very, very slim. However that doesn't mean you can't win some fights on the local circuit and then who knows after that? Depends on the individual(you). What are your expectations? First you will need to go through the training and see how you feel. I see guys making their pro debuts every week on Super Fight League. Some of them are very sloppy and others are much more polished.
Ok , but atleast i get some fight in cage in time :P And again thanks for all info
