Body mechanics applied to shibari.
  • 1.2.1 Anatomical restriction

    Here, anatomy is studied as a tool for understanding the effects of restriction on the body, starting from common positions and figures analyzed from a biomechanical perspective, with criteria for adapting practice to each person.

    Estimated reading time: 5 minutes.

  • 1.2.2 The body (I)

    A first look at functional anatomy applied to shibari: the parts of the body we work with, how they respond, and the risks we need to know about.

    Estimated reading time: 12 minutes.

  • 1.2.3 The body (II)

    A second look at functional anatomy applied to shibari: the body’s systems, how restriction affects them, and which limits must never be crossed.

    Estimated reading time: 10 minutes.

  • 2.1.1 Posture

    Posture covers both the anatomical position of the body and the person’s mental state; working on it through the concept of shisei (posture – 姿勢) allows us to maintain balance and stability and to perform movements safely and effectively.

    Estimated reading time: 7 minutes.

  • 2.1.2 Balance and equilibrium

    Balance is an active state in which the forces acting on the body are offset through small adjustments; learning to use it together with the principle of proportionality allows the person being tied to match their activation to the tension of the rope and reduce the risk of injury.

    Estimated reading time: 11 minutes.

  • 2.1.3 Mobility

    Mobility is the ability to actively control joint movement; distinguishing it from flexibility and elasticity allows us to adapt forms to the capacity of the person being tied and to stabilize their joints safely.

    Estimated reading time: 7 minutes.

  • 2.1.4 Dynamic range

    Dynamic range is the range of motion a joint reaches without being forced or damaged; distinguishing active from passive range allows us to progress in restrictions while keeping the load on the muscles and not on the tendons or ligaments.

    Estimated reading time: 5 minutes.

  • 2.1.5 Activation

    Muscle activation prepares the body to sustain restriction; maintaining it during practice heightens the perception and transmission of erotic stimuli while protecting ligaments, tendons, and nerves.

    Estimated reading time: 11 minutes.

  • 2.1.6 Tension

    Managing tension in body and rope turns the rope into a transmitter of vibrations that allows us to direct stimulation and guide the movements of the person being tied.

    Estimated reading time: 12 minutes.

  • 2.4.3 Posture exercises

    Neutral posture is an active balance built from our support on the ground; practicing it, standing and seated, allows us to recognize how our body distributes weight and to make use of ground reaction force without overloading the joints.

    Estimated reading time: 14 minutes.

  • 2.4.4 Posture and balance exercises

    Control of your own body is the basis for managing the body of the person being tied; practicing posture and balance allows us to move ourselves and the rope ergonomically, with fluid movements that do not distract from the interaction.

    Estimated reading time: 8 minutes.

  • 2.4.5 Video guide: the Velcro theory

    An exercise for creating and managing, between the person tying and the person being tied, a kinetic circuit in which both share the ground reaction force.

    Estimated reading time: 6 minutes.

  • 3.2.2 Anatomical restriction

    Anatomical restriction is created with the body of the person being tied itself. Applying it through muscle activation allows us to limit movement while reducing the risk of injury.

    Estimated reading time: 7 minutes.

  • 3.3.2 Dynamic range

    We are going to start moving the body, which is complex in itself, and look at a concept that is essential in shibari: dynamic range.

    Estimated reading time: 12 minutes.

  • 3.3.3 Forearm Shuto (手刀)

    An exercise for both partners to identify your optimal point of strength on the forearm. It is necessary in techniques that require effective pushing and support, and it helps you maximize efficiency and reduce the risk of injury.

    Estimated reading time: 3 minutes.

  • 3.3.4 Capture

    The person tying offers a point of support on which the person being tied rests part of their weight; in this way, the kinetic circuits of both bodies combine, and that weight can be turned into energy to move them both.

    Estimated reading time: 2 minutes.

  • 3.3.5 Kote Tori (小手取り)

    The grip, or Kote Tori (小手取り), matters because it is the first physical contact between the person tying and the person being tied, and it will shape how the interaction between them unfolds.

    Estimated reading time: 19 minutes.

  • 4.1.1 Anatomy

    Immobilizing the arms not only limits what the upper trunk can do; it also changes the overall posture of the body and affects breathing, balance, and the perception of control.

    Estimated reading time: 10 minutes.

  • 4.4.3 Biomechanics

    A study of the stabilization of the pelvis and shoulders, and of the muscle activation that sustains it, as the basis for building a gote adapted to each anatomy.

    Estimated reading time: 5 minutes.

  • 5.2.2 Wrists

    Estimated reading time: 0 minutes.

  • 5.2.4 Seiza

    Estimated reading time: 0 minutes.

  • 5.2.5 Pelvic muscle control

    Estimated reading time: 0 minutes.

  • 5.4.3 How much force

    Estimated reading time: 0 minutes.

  • Choryoku (張力)

    Tension, both in the body and in the rope. The term is also used for muscle activation.

  • Fuchin (浮沈)

    Fuchin (浮沈) can be translated as “floating and sinking”, “up and down” or “ebb and flow” —like the tide—.

  • Fureru (觸れる)

    It is one of the two terms used to refer to the technique through which different forms of communication and body management are established.

  • Haru Chikara (張る力)

    The term 張る (haru) means “to tense”, “to stretch” or “to activate”; in the anatomical context, it points to the muscles of the core.

  • How physical condition affects shibari practice

    The short answer is that it is not a requirement, but there are nuances worth knowing: what role posture, mobility and biomechanics really play in practice, and how they relate to the erotic experience.

  • Kote Tori (小手取り)

    It is a term from aikido, used in the early formulations of the Yagami Ryu, which in the dojo we adapt as one of the fundamentals of sekibaku.

  • Kuzushi (崩し)

    Kuzushi (崩し) refers to the instant at which balance breaks.

  • Maru (丸)

    It is the circle that always brings you back to the starting point.

  • Shisei (姿勢)

    Shisei (姿勢) refers to body posture, specifically to the neutral anatomical position.

  • Shuto (手刀)

    It refers to the techniques that use the edge of the hand as a point of support.

  • Taijutsu (體術)

    The term is formed by combining two characters:

  • Taijutsu (體術): body mechanics

    The study of the techniques that allow us to understand and use the body during shibari is the second technical area of Sekibaku and, without doubt, the most demanding for students.

  • Tenbindori (天秤取り)

    Under this term we group the strategies and procedures we use to manage balance during the shibari session, for both the tied person and the person tying: the equilibrium between the forces acting on the body —gravity, one's own effort, external actions, the response of the ground—, so that they offset each other and the net result tends toward zero.

  • Tetori Sankaku (手取三角)

    Known as the “triangle theorem”.

  • Toraeru (捉える)

    Literally, “to capture”.
