Which description matches the initial balance progression on flat terrain?

• A. One foot forward.
• B. Feet together with knees locked.
• C. Wide stance with straight legs.
• D. Static stance with feet hip-width apart, slight knee bend, upright trunk.

Answer: (D)

Balancing on flat ground starts with a stable base and proper alignment. The described static stance—feet hip-width apart, knees slightly bent, trunk upright—creates the broad, stable base needed to sense weight and make quick, subtle adjustments. The slight knee bend also cushions the joints and allows easy weight transfer as you begin to move, while an upright trunk helps keep the body's center of gravity over the base of support.

Why the other postures aren’t ideal for starting balance: shifting weight to one foot too early reduces the base of support; locking the knees removes natural shock absorption and makes small corrections harder; and a wide stance with straight legs can feel stable but is stiff and limits the ability to respond to slight perturbations.
