HDT programmes are all about increasing functionality, so they can be used to achieve higher levels of ability. By doing extensive and effective work on the body it should be possible to achieve levels not previously achieved.

There are elements of core functionality that provide a foundation for skill in any area, such as body grip. Different skills require different patterns of muscular connectivity and different physiological acuity.

Body grip is essentially the old 'chest held high' characteristic, however treated with a little more science and method.  Achieving body grip is not simply a matter of 'holding the chest high', rather it is a long developmental process that starts with the baby who has no ability to hold itself up whatsoever, to the grown adult who is an expert in their chosen field.

Weak body grip is associated with poor ability in physical activities, low self-esteem and depressive characteristics.  Strong body grip is essential for overall structural integrity, since the chest is central to the body as a whole. 

Testing for Body Grip 

One way to test body grip is by lying on your front. If you are able to comfortably support the body with the chest with no help from the arms, then this is a sign of good grip.

Physiological acuity varies from skill to skill. Some skills require acuity in the development of hands and fingers and the associated motor connections, such as piano, surgery, and most trades. Other skills require vocal acuity, such as singing, announcing, leadership, sales. Skills that require good body placement, like most sports require yet another kind of acuity.

Developing physiological acuity

Yoga is useful for developing acuity in the body because it stretches and strengthens all the large muscle groups in the limbs and body.

To develop vocal acuity requires extending yoga like methods into the facial muscles to stretch and strengthen there. This is included in the Intermediate and Advanced EmotFit programmes.

To develop manual acuity requires actually practising the skill involved until the required level of skill is achieved. This can be done alongside an HDT programme that improves related functionalities, helping acuity to come more easily.

Measurement

Physiological acuity can to a certain extent be measured by achievement level: getting into the top team, winning competitions.
