Postura abierta (open stance)
Also known as: postura abierta, posición abierta
Una postura abierta coloca ambos pies aproximadamente paralelos a la línea de fondo en el momento del contacto, permitiendo que las caderas roten con potencia a través de la bola sin necesidad de un paso de transferencia de peso.
By planting both feet parallel to the baseline and driving rotation from the hips and torso alone. Players can hit with pace and spin even when on the run — and recover back to the center of the court immediately after contact. On the forehand especially it relies on strong hip-shoulder separation and a pronounced shift from the back foot to the front. Crucially, good ones are not arm-only. They need the same hip and shoulder rotation a stepped-in position produces, generated without the step. It suits low, short balls poorly, where stepping in gives better forward momentum.
The weight shift here is often misunderstood. Without a stepping foot to transfer weight forward. The weight shift happens through a push-off from the back leg and a loading-and-releasing motion of the back hip. The back knee bends on the backswing to load the hip, then straightens explosively as the hips rotate forward — creating a linear weight shift that feeds into the rotational energy of the swing. Players who skip that loading motion produce a genuinely arm-dominant swing that lacks pace and spin despite looking rotational.
Recovery is the hidden advantage. Because neither foot is committed to a crossing step. The player can immediately push off in any direction after contact — left, right, or forward — without first having to unwind from a stepping motion. This is why forehands on the run are hit this way as a matter of course. The player arrives moving sideways, plants, swings, and keeps moving back toward the middle without losing momentum. Stepping across first requires reversing that motion before recovering, and the fraction of a second it costs matters enormously at speed.
Tips by skill level
To feel it hip-driven, shadow swing with your arms crossed over your chest and rotate fully — then add the racquet and try to match that same hip speed.
Add an aggressive shift from the back foot to the front by pushing off the back leg explosively. This adds linear momentum to the rotational power.
Example
Llevado abierto al pasillo del lado de iguales, un jugador planta ambos pies abiertos a la pista, carga la cadera derecha y hace girar una derecha cruzada: no hay tiempo de entrar con paso, pero la rotación completa aporta velocidad.
Why it matters
Modern tennis is played largely from this position. Motion Lab estimates how far your hips turn, which shows whether these shots stay hip-driven or slip into arm-only swings.
How it shows up on video
SwingVantage checks that the hips, not just the arm, are driving the rotation. On video, check that both feet are roughly parallel to the baseline at contact. An arm-dominant version shows minimal hip clearance, a flat swing path and a short or scooped follow-through.
Common mistakes
- Swinging with the arm alone instead of driving the rotation from the hips
- Using it on a ball slow enough to step into, which sacrifices power and depth
- Allowing the back knee to collapse inward instead of loading it properly, reducing hip-drive capacity
- Failing to recover immediately, since there is no stepping momentum to start the return movement
In SwingVantage Motion Lab
Motion Lab estimates how far your pelvis turns from the coiled position to the finish. This separates a hip-driven forehand from an arm swing struck from the same footing.

¿La postura abierta es mala para los principiantes?
No de forma inherente: muchos entrenadores enseñan la postura abierta pronto porque refleja el movimiento rotacional natural. El punto crítico es aprender a impulsar caderas y hombros, no solo el brazo.

- Postura cerrada (closed stance)Una postura cerrada coloca el pie adelantado cruzado por delante del cuerpo en el contacto, favoreciendo una transferencia de peso natural de atrás hacia delante y simplificando la trayectoria de swing para los principiantes.
- Rotación de caderas (hip rotation)La rotación de caderas en el tenis es el giro de la pelvis desde la posición enrollada del backswing hacia el objetivo durante el swing de avance; es el motor principal de la potencia en la cadena cinética.
- Cadena cinética (kinetic chain)La cadena cinética en el tenis es la transferencia secuencial de fuerza de abajo arriba a través de las piernas, las caderas, el tronco, el hombro, el brazo y la raqueta, en la que cada segmento acelera al siguiente para multiplicar la velocidad de cabeza de raqueta.
- Derecha (forehand)La derecha es un golpe de fondo ejecutado con el brazo dominante que cruza el cuerpo desde el lado no dominante; es el golpe más natural y normalmente el más potente del repertorio de un jugador.
- Paso de recuperación (recovery step)El paso de recuperación es el movimiento que se hace inmediatamente después de golpear para recolocarse en la base defensiva u ofensiva óptima antes de la siguiente bola del rival.
- Patrón de movimiento (movement pattern)Un patrón de movimiento es la secuencia de pasos de juego de pies que un jugador usa para llegar a la bola, ejecutar el golpe y recuperar la posición, combinando split step, pasos de aproximación, postura y recuperación.
