Push Hands Karate Drills. Ok. One can look at this video and think that this would never happen in a fight. You have to look into the deeper purpose of the drill to understand its self defense benefits. The over all skills picked up through the repetition of the drill are sensitivity, trapping, and chaining multiple defenses and attacks together. Which is exactly what a self defense situation calls for. Taking away some of your attackers weapons is good, and this is a good drill.
