Heisoku Dachi (sometimes called the Ready Stance) is the fundamental attention stance in most martial arts styles, including Tensoku Ryu. In this stance the heels and toes come together and the arms fall at full natural extension along the outside of the thighs. The fingers are normally straight, but not rigidly straight, and the palms lightly touch the legs. The knees are generally straight, but are not locked. A (very) slight separation between the heels helps improve balance and stability.
Heisoku Dachi is a common initial stance when performing a formal bow or when preparing to begin a Kata. It is the initial stance position assumed when performing our Standard Salutation.
When adopting this stance the eyes should be focused ahead but in a way that allows you to utilize wide peripheral vision. Weight should be evenly distributed across the entire bottom of the foot.
This stance has limited martial applicability. It is primarily used for procedural or ceremonial purposes.
But this does not mean it has no martial uses. You may move from some other stance into Heisoku Dachi as part of a movement sequence – but you would be unlikely to remain in Heisoku Dachi. Of course, you would not have your hands at your sides when involved in a conflict situation.
In a conflict you would move through Heisoku Dachi on your way to some other stance or activity. You would move into Heisoku Dachi because it moves you forward (or back or even to the side) in an erect structural alignment. This can be useful for manipulating or striking at an opponent. While there are exceptions to every rule, it is reasonable to assume you would not be in this posture for long while in a conflict. The stance is inherently unstable should you be pushed or struck while in this position.
