The abdominal muscles insert on the pelvis (pubis or iliac crests), but they do not all have a contractile part in this lower zone, between the pubis and three fingers below the navel. Sometimes we lose some of the strength and capacity of contraction in that area.
Nevertheless, this contraction should biomechanically follow that of the perineum to allow abdominal contractions to go upward (the inverse being hyperpressive, it should be avoided in a vertical position and should be limited to the visceral massage laying down).
To feel this area, first place your hands one on top of the other under the navel, above the pubis. Feel the heat under your hands, you can even rub the entire area to wake her sensorially.
Then visualize the flame of a candle in front of you … .gently blow it … .. then let yourself inhale, “opening your nostrils”, as if you were breathing a flower …… And quietly repeat. Do you feel under your hands, at the very beginning of the action, the lower belly that is brought back to the spine? with the inhalation this area relaxing ?
If the image does not speak to you, try to “make bubbles underwater”
You feel ? a little ? An intention of movement may be? Sensations increase gradually with practice, persevere!
