Nonsense
Nothin is more real than your opponent waiting for you to hit him
In one of my martial-arts classes, the sifu introduced us to a close friend who was visiting the country. This guy was like a JCVD type: kick master.
I’d never seen those kicks done in real life and was shocked at the speed and ferocity when performed by a high-level practitioner. He sparred a little without the kicks making contact. In the blink of an eye he could launch knee and feet offensives that, if he’d desired, would seriously rock your world.
Now I’m well aware of practicalities. Weather, landscape, clothing, available space. However, to suggest such a skilled and athletic individual couldn’t utilize these specific talents in a number of situations is ridiculous.
