At Defense That Works, we focus on the most practical, direct, and effortless ways to defend against weapons with nothing but our bare hands. This is practical street defense, NOT SPORT. The techniques that we practice here are extremely dangerous, very powerful, and will leave people hurt, so if you wish to study please exercise caution. ?If you want to use this for MMA or Karate tournaments, you will be disqualified and leave people injured. For this reason, we do not allow anyone under the age of 18 to study with us and prefer that students have some prior martial arts experience. ?All of what we practice can benefit seasoned martial artists or complete beginners. ?This is a great addition to any prior training. ?Add it to your system.
