Learning Breakfalls should be your first lesson in a Brazilian Jiu-Jitsu or any other grappling martial art school.
You just don’t want this to happen to you and if you didn’t learn breakfalls properly it’s just a matter of time until something like this really happens to you.
WARNING: This is Why Jiu-Jitsu is NOT for Everyone. BJJ in Wrong Hands!
WARNING: Terrible Leg Break and Extremely loud Fracture as a result of Heel Hook
