I see many posts on social media in my area asking where to go for self-defence training. From this you get a lot of people giving their opinion and what is often suggested is Brazilian Jiu-Jitsu (BJJ) . However I feel that this advice respectfully is coming from people with little or no expertise or experience of physical altercations and violence!!
BJJ and Judo are both highly respected combative sports that emphasise grappling and ground techniques. While they are excellent for sport, competition and fitness, there are several reasons why they are not effective systems for self-defence in real-world scenarios.
