 Here's some details on the cup-tang, what I also call the kua-tang. It's called the elbow strike. So, like I mentioned, the hand comes up, near your ear, and then down at the chest level when it stops. Notice that the elbow does a circular action. So if I'm facing this way, I'm going to saw that elbow comes down like a circle, going backwards and forwards. This is important because all you want to do is actually strike the elbow like a knife this way. So if I'm facing this way, you can see that it's moving in circles. The reason we drop our shoulder is because it's high that we don't actually drop our weight onto our elbow. If our shoulder is low, the weight actually goes down by part. So when you drop your shoulders, you get that weight on that shoulder. The second thing I also show you is to use this and pull. So when you pull back with this hand, it actually increases the power of this hand. So if we're going this way, notice that this pull actually increases the power of the downward action. Because you're pulling your muscles this way and then you're also throwing your muscles this way. So you engage your back muscles and your waist muscles when you're pulling back with the other hand. So that's some details of the elbow strike or the cuts out that you can add to your form.
