What you start with

New starters always commence class with a significant amount of muscular tension.
This is usually supplemented with emotional and psychological stresses.
Typically the student is only vaguely aware of these problems.

The entire beginners syllabus was designed to introduce people to this tension.
To train their nervous system to actually feel it in their own body.
It usually comes as a surprise; and this is the drawback of habitual poor body use: the dulling of the senses.
