Cada enero, la promesa de un vientre plano regresa con la misma constancia que el invierno. Esta vez, España mira hacia Japón, donde tres técnicas de ejercicio —la toalla enrollada, la respiración larga de Ryosuke y el método postural de Sakuma— han cruzado fronteras digitales prometiendo resultados con lo mínimo: tiempo, espacio y voluntad. En un mundo saturado de gimnasios y equipos costosos, estas prácticas ofrecen algo más antiguo y más humano: la idea de que el cuerpo puede transformarse desde adentro, con paciencia y presencia.
- Tres métodos japoneses se han vuelto virales en España justo cuando millones buscan cumplir sus propósitos de año nuevo relacionados con el cuerpo.
- La urgencia es real: cada técnica promete resultados visibles en minutos al día, sin salir de casa ni gastar en equipamiento.
- La tensión subyacente es la de siempre —el deseo de cambio rápido frente a la realidad del esfuerzo sostenido— y ninguno de estos métodos ha sido validado científicamente de forma concluyente.
- Aun así, la accesibilidad es su mayor argumento: una toalla, el suelo, la respiración propia y una silla son todo lo que se necesita para comenzar.
- El movimiento está aterrizando en la vida cotidiana de quienes buscan rutinas que quepan en los márgenes del día, no que reorganicen su agenda entera.
Cada enero resurge la misma resolución: un vientre más plano, un cuerpo más cuidado. Este año, España ha encontrado inspiración en Japón. Tres técnicas de ejercicio han circulado con fuerza en redes sociales, unidas por una promesa común: resultados abdominales sin gimnasio, sin equipos caros y en pocos minutos.
La primera es el ejercicio de la toalla, una rutina de cinco minutos basada en contracciones isométricas. Se enrolla una toalla, se coloca bajo la zona lumbar mientras se está tumbado boca arriba, con los pies en punta hacia adentro y los brazos extendidos sobre la cabeza. La posición trabaja el recto abdominal y los oblicuos sin necesidad de movimiento articular. Puede hacerse en cualquier rincón: un dormitorio, una habitación de hotel, una oficina.
La segunda técnica, atribuida a Ryosuke, se centra en la respiración. De pie con una pierna adelantada y el peso en la pierna trasera, se inhala durante tres segundos y se exhala con fuerza durante siete, tensando todo el cuerpo. Más que un ejercicio convencional, es una forma de dirigir la energía hacia el núcleo corporal con cada espiración.
El tercer método lleva el nombre de Kanichi Sakuma, un entrenador japonés que parte de una premisa distinta: la corrección postural. Su teoría sostiene que la manera en que sostenemos el cuerpo durante el sueño, el trabajo o el paseo determina si los músculos abdominales y dorsales se activan o se atrofian. La rutina combina ejercicios en el suelo y en silla, con elevaciones de piernas, sentadillas sobre las puntas de los pies y movimientos de cadera que buscan alinear la columna y tonificar glúteos y muslos.
Lo que une a los tres métodos es su accesibilidad radical. No exigen desplazamiento ni inversión económica. Caben en los márgenes de la vida ordinaria. Si realmente entregan el vientre plano que prometen es una pregunta que el entusiasmo viral aún no ha respondido. Pero para quien empieza el año con la esperanza de un cambio, ofrecen algo esencial: un punto de partida.
Every January, the same resolution surfaces: a flatter stomach, better fitness, the body you promised yourself. This year, Spain is looking east. Three Japanese exercise techniques have gone viral across the country, each promising abdominal results with minimal equipment and time. What they share is a kind of elegant efficiency—a rolled towel, five minutes, a patch of floor. No gym membership required.
The simplest of the three is the towel exercise, a five-minute routine built on isometric principles. The idea is straightforward: contract your muscles without moving your joints. You roll a towel, sit on the floor with your legs stretched out about twenty to twenty-five centimeters apart, then position the towel behind your lower back. Lie on your back with the towel beneath your waist. Your feet should angle inward like the point of a triangle. Raise your arms overhead, palms down, almost touching the ground. Then bring your pinky fingers together and draw your toes inward until they meet. Hold this position for five minutes. The exercise targets not just the rectus abdominis—the muscle responsible for bending your torso and drawing your ribs toward your pelvis—but also the internal and external obliques along your sides. It's the kind of routine you can do anywhere: in your bedroom, in a hotel room, in the corner of an office during lunch.
The second technique comes from Ryosuke and centers on breathing. Stand with one leg forward, the other back, weight shifted entirely onto your rear foot. Your glutes should feel stretched. Raise your arms overhead. Inhale slowly for three seconds, then exhale forcefully for seven, tensing every muscle in your body as you do. The Japanese recommend repeating this for two to ten minutes, as many times as possible. It's less a workout than a breathing pattern, a way of channeling force through your core with each exhale.
The third method bears the name of Kanichi Sakuma, a Japanese trainer who built his approach on a different premise: posture correction. The theory is that how you hold your body during ordinary moments—sleeping, working, walking—determines whether your abdominal and back muscles engage or atrophy. Fix your posture, Sakuma argues, and you don't just lose weight; you tone your abdomen, glutes, and thighs. The method involves a series of floor and seated exercises. Lie face down with your hands behind your neck, elbows extended, chin nearly touching your chest. Cross your ankles. Lift your legs and head together, holding for ten seconds. Repeat three times. In the next variation, press your legs together instead of crossing them. Then bend your knees and cross at the ankles so your calves are perpendicular to your thighs, lifting three times for ten seconds each. Seated in a chair, drop your shoulders away from your head while keeping your spine straight, then lift one leg by pressing through your hips. Hold for three seconds, switch legs, repeat ten times. Finally, rise onto your toes, interlock your fingers, extend your arms fully overhead, lower into a squat, hold for three seconds, and repeat twenty times.
What binds these three approaches is their accessibility. They require no membership, no expensive equipment, no commute. They fit into the margins of ordinary life. Whether they deliver the flat stomach they promise remains a question the viral enthusiasm has not yet settled. But for anyone starting the year with the familiar hope of a changed body, they offer something that matters: a place to begin.

If you correct your posture, you achieve not just weight loss but also toning of the abdomen, glutes, and thighs— Kanichi Sakuma's method philosophy
La Conversación del Hearth Otra perspectiva de la historia
Why do you think these Japanese methods caught on in Spain specifically, and now?
New Year's resolutions create a moment of openness. People want to change but don't want friction. A rolled towel and five minutes removes every excuse.
The towel exercise sounds almost too simple. How does lying still for five minutes actually change your body?
It's isometric work—your muscles are contracting hard, just not moving. The tension itself, held, builds strength and endurance in the core. You're not doing reps; you're holding tension.
And the breathing technique—is that actually exercise, or is it more psychological?
Both, probably. The breathing forces you to engage your entire core while exhaling. It's a way of making your abdominal muscles work without traditional movement. Whether it's as effective as claimed is another question.
The Sakuma method seems the most involved of the three. Why include posture correction as part of abdominal training?
Because posture determines which muscles fire during daily life. If you're slouching, your core isn't working even when you're moving. Sakuma's idea is that fixing how you sit, stand, and sleep means your muscles are engaged all day, not just during exercise.
Do these methods work better together or separately?
The source doesn't say. But they're different enough that someone could rotate through them or combine them. The towel exercise is passive; the breathing is rhythmic; Sakuma is active. Together they might hit different angles.
What's missing from this story?
Scientific evidence. Testimonials. How long before someone actually sees results. Whether these work better than traditional ab exercises. The enthusiasm is real, but the proof is still viral, not verified.
