This technique was developed by Dr. George Goodheart, a chiropractor and creator of Applied Kinesiology in 1964. His work brought awareness that the body had the ability to respond to stress with precise indicators via the muscles. Muscle testing is used to determine the body's imbalances, needs and communication gaps through a non-invasive and holistic procedure. Muscle testing is used to obtain information on energy blockages, nutritional deficiencies, food sensitivities and organs' levels of functionality.

Once a person's body is balanced, muscle testing leads to honest answers to "yes" and "no" questions, provided answers are formulated with clarity.

The science behind muscle testing

"While muscle testing in itself is not hard to do, understanding the science behind muscle testing is hard to explain... The body functions with energy; human body cells have a resonant frequency at about 1000 KHz, and electric currents circulate throughout the body, via, among others, the meridian system. As with any energy system, certain external elements can cause a disruption, reduction or increase in the frequency. When the body is in the presence of an element that has a negative effect on the energy system, such as an allergen or a certain word that has a negative connotation to the recipient, or a question that simply has a negative answer, the energy levels of the body will be affected in a negative way, thereby causing a drop in the energy and weakening of the muscle, resulting in a "no" answer. The same can be said for elements, words or questions that have a positive effect on the energy system, they will cause an increase in the body's frequency and a strong muscle, indicating a "yes" answer."
