The parsimony of effort theory poses practical problems for movement observers. There are only four motion factors and eight effort qualities, which makes the categories for classifying effort quite general and abstract.
For example, compare the actions of driving a shovel into hard soil and passionately embracing a loved one. Superficially the two actions do not look at all the same. Yet increasing pressure (the contending quality of the motion factor of weight) is likely to be present in both actions.
To use effort theory effectively, the observer must be able to identify the basic elements that combine to produce a variety of actions that look nothing alike.
The only way to use the elegant theory of effort effectively is to practice by moving, observing, and investing in an “effort bank.” Find out more in the next blog.
