Did you know that martial arts isn’t just good for your body – it’s good for your mind? Researchers compared the brains of black belts to complete martial arts newbies… And they found that the black belts had structural differences in the areas of the brain associated with controlling movement. That means – the force behind a powerful move doesn’t just come from your physical strength, it also comes from your mind and experience. That’s why a martial arts expert doesn’t have to be the most muscle-y guy in the room to lay out his or her opponent. Case in point – Bruce Lee was 5’8” and only weighed 135 pounds.
