The neutral sit is built from right angles

A stable sit looks casual from the outside, like sitting in a deck chair at 240 km/h. The position underneath is precise, and the precision is what makes it teachable: the neutral sit is built from right angles, and when one of those angles is wrong, the sit misbehaves in a predictable way.

The reference geometry

• Knees bent 90°, at shoulder width, with heels aligned below the knees.
• Hips at 90°, torso perpendicular to the relative wind, back straight.
• Arms out at 90° for stability, feet flat with even pressure on both.
• Eyes to the horizon. Looking down drops the shoulders and the whole position follows.

Rehearse it on the ground until the shape is available without thought: five holds with eyes open, five with eyes closed. In the air, the wind gives you honest feedback about every angle you missed.

Faults and their causes

The three fault patterns that fill every coach’s debrief notes each trace to specific geometry errors, which is what makes video review so productive at this stage.

Backsliding. The silent one, because a solo flyer covering ground toward the next group cannot feel it. Causes: wind pushing the knees toward the chest, torso leaning forward with the arms trailing behind, looking down, tired shoulders rolling forward, feet and knees tucked too close together.

Fallout to the back. Toes pointed at the ground, lower legs blown around, arms too far forward, back not straight.

Fallout to the belly. Knees bent past 90° with heels tucked under and wind on the shins, or too much arch.

Uncontrolled rotation. Asymmetry anywhere: uneven leg or arm pressure, legs too close together, heels out of line with the knees, one upper leg higher than the other.

Fall rate lives in the legs

From the neutral sit, the fall-rate ladder runs knee-fly, sit, stag, stand, each rung presenting less leg surface to the wind and falling faster, each with less inherent stability than the last. Move one rung at a time and hold each stable before moving on. Turns come from the legs too; the arms are for stability, and steering with them is how rotations start.

A flyer who owns the reference angles can self-diagnose from video: name the fault, name the geometry error behind it, fix that one thing on the next jump. That loop, one correction per jump, is the whole method at this stage.
