What is the most practical defensive martial art?
Which of the four martial arts styles that you mentioned is the easiest to learn?
I'm not sure about the complexity of learning these martial arts as they all require different levels of commitment and training, however Judo might be considered as one of the easiest to learn, as it focuses on using an opponent's body weight and momentum against them, rather than relying solely on brute strength or highly technical maneuvers.
