Obverse and Reverse Techniques
An obverse technique is a hand technique performed with the same hand as the stance. For example, if you are in a left L stance and you have punched with your left hand, that is an obverse punch. If you are in a right walking stance and have punched with your left hand, this is a reverse technique.
Left and Right Stances
Any stance with 50/50 weight distribution that has length as well as width (e.g. walking stance, fixed stance) is named by the front leg. Any stance that has more weight on one leg than the other is named by the leg that bears the most weight (e.g. L-stance, X-stance). Stances with 50/50 weight distribution that have width but no length (e.g. parallel stance, sitting stance) are neither a left nor right stance.
Bending Stance vs One-Legged Stance
In a bending stance, the single supporting leg is bent. In a one-legged stance (as found in Po-Eun), the supporting leg is straight.
Outward and Inward Techniques
•Outward Technique: The technique is travelling outwards from the centre
•Inward Technique: The technique is travelling inwards towards the centre
Rising Technique
A rising technique rises above the performer's head.
Guarding Blocks vs Reaction Hand to Hip Blocks
In traditional Taekwon-Do, a guarding block has the secondary hand up near the primary hand ready to quickly perform another technique. A reaction hand to the hip technique is traditionally believed to give you 'reaction power' – increased force in your strike or block. In practical self-defence Taekwon-Do terms, the purpose of a guarding block is the same as the traditional application, however the reaction hand to the hip would be used to pull an opponent (perhaps off-balance and onto a technique), escape from a grab, and as a powerful base to hold an opponent's hand/wrist on your hip.
