Stance Work: Horse, Bow, and Empty Step

樁功

Three stances underpin nearly every standing movement in the curriculum. Getting the weight distribution right is most of the work.

Three stances underpin nearly every standing movement in the curriculum. Almost all of the work is weight distribution, and almost all of the injuries come from the knee going somewhere the foot did not.

The universal rule

Before any individual stance: in every weighted position, the knee points the same direction as the foot, tracking roughly over the second toe. If the knee drifts inward while the foot stays put, the joint is being loaded in rotation, which is precisely what it is worst at tolerating.

This single check prevents most stance-related knee problems. It is worth more than any amount of instruction about depth, and it is easy to verify — look down.

Horse stance馬步

The symmetrical base. Feet parallel, roughly one and a half to two shoulder-widths apart, weight evenly split, knees bent and tracking over the toes, pelvis neutral, spine vertical.

  1. 01
    Set the feet

    Parallel, or with the toes turned out no more than about fifteen degrees. Turning the toes out further and then bending the knees is the most common cause of knee drift.

  2. 02
    Sit, do not lean

    The movement is downward, as if lowering onto a high stool. If the chest travels forward, you are hinging at the hip instead of sinking.

  3. 03
    Check the shins

    They should be close to vertical. A knee that has travelled forward past the toes has shifted the load onto the joint rather than the muscles.

  4. 04
    Neutral pelvis

    Neither tucked hard under nor tipped forward into an arch. Let the lower back keep its natural curve.

  5. 05
    Start high

    Beginners should sit barely at all — a few centimetres. The classical low horse stance is a conditioning posture, not a starting position.

Horse stance appears in the Eight Brocades in movements two and seven, and throughout the martial section of the Zen Gong sequence.

Bow stance弓步

The directional stance. Front leg bent, back leg extended but not locked, weight roughly seventy per cent front and thirty per cent back. Front foot points forward; back foot turns out around forty-five degrees.

Empty step虛步

The mobile stance. Nearly all the weight — around ninety per cent — sits on the back leg, which is bent. The front foot rests lightly, either on the ball or the heel, carrying almost nothing.

The name is exact. 虛 means empty or insubstantial, and it is the same character used for the hollow armpit and for the hollows tapped in Pa Ba Xu. The front foot is empty in the sense that it could be lifted instantly without any weight shift first.

Building capacity

Stance work develops slowly and rewards patience more than effort. A reasonable progression is to hold a high horse stance for thirty seconds, three times, and add ten seconds a week — never lowering the stance and extending the time in the same week.

The failure mode to avoid: going deep because deep looks serious. A high stance held with correct tracking builds usable capacity. A deep stance with the knees caving builds a knee problem.

How low should a horse stance be?
Much higher than you think, especially early. A few centimetres of sink with correct alignment is more useful than thighs-parallel with the knees collapsing.
My thighs burn after thirty seconds. Normal?
Yes. These are unfamiliar isometric positions. Burning in the quadriceps is fatigue; sharp pain at the knee is not.
Should my feet be parallel or turned out in horse stance?
Parallel, or turned out no more than about fifteen degrees, with the knees tracking to match. Wide toe-out with forward-pointing knees is the injurious combination.
Can I do stance work with knee problems?
Often yes, at a much higher stance and with careful tracking — but check with a clinician or physiotherapist first, especially with meniscal or ligament history.
Does the app check my stance?
It reads knee angle and rough alignment from the camera. It sees gross errors reasonably well and subtle rotation poorly. See Reading a Posture Score.
