Don’t Blame Me, It’s Isaac's Fault


Student 1: “Dude you almost broke my arm!!”

Student 2: “It’s not my fault, it’s Isaac’s fault”

Student 1: “what are you talking about, who’s Isaac?”

Student 2: “Let me tell you a little story”

“Once upon a time, there was a boy named Isaac who lived in a small town in England. Isaac was a very curious boy, and he loved to learn about the world around him. He would spend hours exploring the woods near his home, and he would often ask his parents questions about the stars and planets.

One day, Isaac was playing with a seesaw when he had an idea.

"What if I could make a lever that could lift heavy things?" he thought.

Isaac went to his workshop and started building a lever. He made a long arm with a fulcrum in the middle. He then attached a heavy weight to one end of the arm and a lighter weight to the other end.

When Isaac pushed down on the lighter weight, the heavier weight lifted up. Isaac was so excited that he ran to tell his parents.

"I invented a lever!" he said. "It can lift heavy things!"

Isaac's parents were proud of him. They told him that he could use his lever to help people.

Isaac was happy to help people. He used his lever to lift heavy objects, such as rocks and logs. He also used it to help people move furniture and other heavy objects.

Isaac's lever made many people's lives easier. They were grateful to Isaac for his invention.

One day, a farmer came to Isaac with a problem. He had a large rock that he needed to move, but he couldn't do it by himself. Isaac offered to help him with his lever.

The farmer was amazed at how easily Isaac was able to lift the rock with his lever. He thanked Isaac profusely and told him that he had saved him a lot of time and effort.

Isaac was happy to help the farmer. He knew that his lever could help people in many ways.”


Student 2: “You see my body positioning gives me a mechanical advantage when I use the cross-body armbar. This is because of the ratio of the force required to break your arm to the force that I can generate. 


Student 1: “What?!?!”


Student 2: “This ratio is determined by three things:

  1. The length of your arm (the lever), which is the distance from the fulcrum (my hips) to the point where your arm is bends (the elbow).
  2. The angle of the lever/arm, which is the angle between the lever arm and the attacker's arm (palm facing up)
  3. The strength of my muscles, and in this case my whole body.

The longer the lever arm, the greater the mechanical advantage. This means that I will need less force to break your arm. The greater the angle of the lever arm, the greater the mechanical advantage (in this case palm turned up with the arm extended). This means that I will need less force to break the arm. The stronger my muscles, and how much of my body I can use, the greater the mechanical advantage I will have. This means that I will need less force to break your arm.”


Student 1: “What are you talking about!?!?!


Student 2: “This is simple Newtonian physics, based on Newton’s levers, so clearly it’s not my fault, I didn’t invent this stuff Newton did, it’s obvious Isaac’s fault”

Student 1: “Don’t be a D#@k!”

Student 2: “...Besides, you know you were caught you should have tapped”.


The moral of the story is:

  1. Leverage enables us to attack an opponent’s joints in the most efficient possible
  2. Using our entire body versus just our muscles(strength) is not only more efficient, it generates more force and is ultimately more effective
  3. Tap early and tap often.
  4. Don’t be a D@#k.
