Is there a way to know how hard to press when using the Reflexology and Acupressure techniques DVD's?

The best way to learn how much pressure to give during a technique is to take a class on reflexology or acupressure, or another option is to make an appointment with a professional and get a treatment.

Another way to answer the question is that it should feel good. Even if there is some pain, it may be beneficial as long as it is a good-kind-of-pain.
