Muscle testing is also known as applied kinesiology (AK). The basic idea behind AK is similar to one of Sir Isaac Newton’s Laws of Motion, which states “for every action in nature there is an equal and opposite reaction.”

Applied kinesiology takes this concept and applies it to the human body. This means that any internal issues you may be experiencing would be accompanied by a related muscle weakness. Following this thought process, you should be able to perform a muscle test to diagnose underlying conditions and issues.

For example; you have a muscle test performed and your bicep is deemed “weak.” A person performing the muscle test with a standard view of medicine, might suggest working out your biceps more at the gym.

However, a person following the principles of applied kinesiology may suggest that you have this weakness, because of an underlying problem with your spleen. Most individuals can carry it out successfully whether for their own health or for someone else’s.

To conduct a ‘muscle test’ you need two people; one stands in front of the other and both face the same way, i.e. the person behind is looking at the back of their partner’s head. The one in front raises their arm to shoulder level with the arm pointing sideways, palm down. He or she then tries to resist downward pressure as the person behind them puts one hand on the partner’s outstretched wrist and the other on their opposite shoulder.

The person who is behind pushes firmly down on the outstretched wrist/arm to get a rough guide to the resistance the person in front has, against their arm being pushed down.

Once this general level of resistance is experienced, the test is repeated but this time the person in front asks the health question they want the answer to.

Eg. Do I have sufficient vitamin D levels?
If you do not have sufficient levels, you will be noticeably less able to resist the downward pressure than when your resistance was being measured at first. If you do have sufficient levels, you will have full resistance.
