Over the last few days, I have been thinking of which martial art to study. I have done Tae Kwon Do in the past, but I have stopped praticing it years ago. Now I have been thinking of taking up another martial art in my spare time. Any recommendations? I have never done wrestling or anything of this sort, so I wonder which martial art I, as a 24-year-old can pick up. I am not aspiring to break into UFC, rather I want something good for my body and to be able to defend myself in extremis.
