By working with intensity, alignment and precision in yoga, you get a
great sensitivity in the lower limbs and hips so important that we can
not get an idea of the benefits that our body receives.
The lower back is decongesting and so on we can experience the feeling of support without weight, of lightness.
Both the stretching in the entire pelvic area and the ease of so many muscles that pass through it, are very important to feel a clear unlocking in this structure.
When Tadasana's stance is lost it means that we lose the inertia of
rise and the body tends to fall, the pelvis suffers a setback, loses
the alignment of the posture and the stability dissipates with which
the weight begins to fall back to the heels and a physical depression
takes place whose origin comes from the excess of muscular tone and effort.
Thus breathing is greatly affected producing a change in mood and a
loss of oxygen in the body. If this happens there is a lack of
consciousness in the body, breathing becomes more unstable, the
sympathetic nervous system is activated as a way of exit or survival,
clearly losing the body-mind connection.
Too much muscle tone in the body produces tension therefore you have to work with balance between intense muscular action and a relaxed calm not too lax. The way you support yourself in the postures in your bone structure helps the sympathetic system not to trigger access to a support from the bone structure without so much muscular action.
For example in Utthita Parsvakonasana, the support in the head of the femur of the flexed leg gives rise to an internal looseness in the hip and the muscles that protect it therefore a deep inner calm occurs, working with intensity the rest of the body.
