Without a doubt, Navy SEAL and BJJ expert Jocko Willink on “real” martial arts is worth hearing out. He mentions that the best thing for self-defense is a concealed firearm. Martial arts won’t always prove effective against certain opponents after all. After making that point, he goes on to say that BJJ is one of the best self-defense martial arts as well as wrestling.
Willink includes weapon-based martial arts, too, but he makes a lot of smart statements in his interview. In fact, he mentions that the answer isn’t always BJJ, and that discipline is what matters. The solution is different for everyone, and Willink knows what he’s talking about.
