The Shita Tsuki, or more commonly called the short punch, is one of my favorite techniques to use in GKR Karate. I also believe it to be one of the most useful. The short punch is typically useful in a situation where the opponent has grabbed you by the clothes and is holding you close. The shita tsuki gives you a few moments of breathing space as well as a few seconds to think about your next move. So, while it is a strike, it has a more defensive background.
The short punch is hands down the easiest performing strike in GKR. Start in a standing position with both hands in the shape of a fist pulled tightly against your waist. Your palms should be facing towards the ceiling. Then, simply punch forward towards your opponent. Keep your hands and wrist tensed as tightly as possible; keeping them soft can hurt your wrist. Do not rotate your wrist at all. Keep your arm extended with your fist pressed firmly against your attacker. Another tip is to tighten your elbow and keep it as close to your belly button as possible and keeping your stomach tight at the same time. This way, if your opponent tries to close the distance again, your arm acts as support and the distance cannot be closed.
This technique should be practiced often, preferably against something heavy, to develop wrist strength and power. Without a lot of practice, this strike won’t have much of an effect. Here are a couple of things to remember:
1. Keep your arm horizontal when delivering the strike. This is absolutely vital to the success of the strike.
2. Keep your wrist tight and develop your wrist strength. A lack of either can result in damage to your wrist.
3. Take advantage of the few moments you have to hit the opponent with a counter strike. The short punch will throw them off guard so they will not be expecting it.
