Question

An exert can move his hands faster and break a brick how is it possible

Answer 1

Answer:

Punch a brick with your bare hand, and if you are untutored in the martial arts, you may break a finger. Punch it with the proper force, momentum, and positioning, and you'll break the brick instead. “Amazingly, there are no tricks involved,” says Michael Feld, a physicist at MIT.

However, there's an old trick to use when it comes to breaking bricks. Simply place your fingers under one side of the brick, and just as you're about to hit the brick you flip it up a little and hit it with your other hand, making it smack against the surface below. Boom. Broken.
