Ballroom & Latin American Poise
In the book “The Ballroom Technique” of Imperial Soсiety of Teachers of Dancing (ISTD), based on Alex Moore’s “Revised Technique” (last edition in 1994) we can find a description of Ballroom Poise.
The book says:
Stand in a natural upright position with knees slightly flexed, body inclined forward from the ankles, braced at the waist with shoulders relaxed at normal level, and with no tension in the chest, body weight forward over the balls of feet with the feet flat.
The poise as Lady will be the same as described for Man, except that she would be poised slightly backwards from the waist. This backward poise must not be exaggerated.“
