In martial arts, is it true that technique beats muscle? I highly doubt that a scrawny kid with kicking skills can beat a crossfitter.
I’m 6’2” and 160 pounds, so I’m tall, but not that built. However, I’ve casually trained jujitsu for several years. About 6 months to a year ago a new guy started to come into the gym, about 28, an inch taller than me, with about 70 more pounds of muscle. He looked about like this, but without the bat:
This guy could obviously crush me in any contest of strength with little difficulty. Even more, he didn’t ever want to go any less than 100% effort. However, I could still beat him in spite of his physical dominance due to my training. Even more, another guy who trained with us was about 5’7” and maybe 130 lb, and I would watch him repeatedly tap this guy twice his size. It was quite impressive to watch.
So, to answer the question, yes, a scrawny kid with good training can most certainly beat a stronger opponent in a fight.
