I'm a 17 year old male, 6 foot 3, weighing at around 95 kg (210 pounds or 15 stone). I've been watching MMA for a while and I have a deep interest for it and so now I think it's time I actually start fighting myself. I may have left it too late to be able to make a good career out of it but that doesn't matter to me I'm just interested in fighting and also for self defence. However I'm not sure which martial art I should learn. When I fight competitively I would like it to be MMA but I don't know what to focus on at the start. I'm pretty tall and heavy (not fat though) and pretty strong too. I've also got good reach. I lack stamina ,flexibility and I'm a little slow too but they are things I will be looking to improve. So what do you guys think is best for me? Any suggestions would be appreciated. Also if you need any more information just ask.
