I've been thinking about sambo and leaning towards it the most but I am now also considering krav-maga and kajikembo(I think I spelt right). only have time for one as I like to completely focus on one style at a time. I'm looking mostly for general self-defense that could also be used in some casual wrestling matches with friends. Also, I'm a bit out of shape so I want to try and get back into shape and burn some fat. Thanks.
