Human beings throughout the ages, in most countries and cultures have learnt how to fight and defend themselves. Some if not all cultures however, have developed their fighting instincts over the years from simple survival tools, to the point where they reach the state of an art form. We nowadays call them the Martial Arts.
Most of today's Martial Arts are similar and tend to look the same, as they all have the purpose of teaching a human being to defend themselves against other humans. They use the human body’s basic physical movements or principles of movement in both attack and defence. Whether your particular Art is Barehanded or weapons based like Arnis, Escrima or Kali, (Filipino Arts which I specialize in) all these systems share these basic principles in their motions.
While most fighting systems are similar for humans, they usually evolve to suit depending on those that organize, teach and learn. With this evolution some systems develop styles that can specialize and develop their own particular qualities and attributes, even teaching methods that are different to other styles.
