“Every 20 pounds equals a belt…and every 10 years equals a belt.”
And you know what a big deal a belt is in Brazilian Jiu Jitsu.
There are many fantasies and delusions people bring to martial arts, most of them fed by the movies, but also by word of mouth mythologies. This is where we hear about “dim mak” (death touch) and about some guy taking out three or four people effortlessly because they are a master of this or that fighting art. You can even see some videos of such feats, so its not completely delusional. But its mostly delusional.
I can tell you from my experience and the experience of my friends and teachers, many of whom are very highly trained. Weight matters. Strength matters. Youth matters. These are all qualities an opponent can bring to a fight that will put a big “thumb on the scales.” Martial arts training is one factor among many in any fight. An old martial adage says, “First courage, then power, then skill.” Courage means you don’t run. Then power. Now, their algorithm isn’t exactly correct, in my opinion. I think there are many 30 and 40 year olds who are stronger than 20 year olds of the same size and fitness level. I think this is even scientifically accurate (not just observation). I’ve heard strength peaks somewhere between 25 and 30. But the idea is sound. Martial arts skill is one arrow in the quiver. Its an equalizer, but not a magic bullet (or wand).
