Hello all, I joined this forum because I am to gain some insight into Martial Arts to help my 12 ( almost 13 year old ) son. For almost a year , he has been training online with Capoeira nation training videos and was very interested in that form. He was very disciplined and would do this every day until he he became increasingly verbally frustrated and complained that he needed a real instructor because he couldn't see himself clearly to know if he was doing things right. I could not find any instructors for him that were close by and affordable. There is only ONE that I could find and it is far from my house and was more than I could afford. I looked into USA Karate, because some of my friends go , but he seemed resistant and was really insistant on Capoeira. Now recently, his brother began to work next door to a TKD/ Pasaryu center. The Master is Kang Rhee. It is convenient and affordable. After hanging out at his brothers work, right next door, he asked to sign up. By his reasoning, Capoeira was not going to happen so might as well. I signed him up and he has begun going every day. It's been 2 weeks. So I am here looking at these forums, and not really sure what I am asking. I just want to be helpful to him because I can tell he is passionate and disciplined. After browsing around the forums and doing searches I have read various things and just want to ask some questions. Someone said in one of the threads that Kang Rhee was not known for producing fighters but for his forms. Is this a bad thing? What is the difference? Pasaryu is a style that is developed by Kang Rhee himself but does not appear to be widely known or widespread. Is this something that is okay? Is it common to mix and match Martial arts styles? For example, can someone become proficient in one Martial arts style and then switch to another. I doubt that his passion for Capoeira is going to go away and if he eventually finds an instructor how realistic is it to switch back and forth between styles? Finally, I have several friends in USA Karate, and I think they do more MMA. I have realized after reading these forums that MAYBE I should be alarmed that my friends kids just joined last year and already green belts?
