The link between exercise and psychology has long been recognized. In 1899, William James discussed the importance of exercise, writing it was needed to "furnish the background of sanity, serenity...and make us good-humored and easy of approach." Other researchers noted the connection between exercise and depression, concluding a moderate amount of exercise was more helpful than no exercise in symptom improvement. Additionally, meeting exercise requirements can also aid in alleviating symptoms of avoidance disorders and anxiety, while also providing a higher quality of life for the patient in terms of physical health. 
Imagery (or motor imagery) can be defined as using multiple senses to create or recreate experiences in one's mind. Additionally, the more vivid images are, the more likely they are to be interpreted by the brain as identical to the actual event, which increases the effectiveness of mental practice with imagery. Good imagery, therefore, attempts to create as lifelike an image as possible through the use of multiple senses (e.g., sight, smell, kinesthetic), proper timing, perspective, and accurate portrayal of the task. Both anecdotal evidence from athletes and research findings suggest imagery is an effective tool to enhance performance and psychological states relevant to performance (e.g., confidence). This is a concept commonly used by coaches and athletes the day before an event.
In 1996, as a result of a three-year research project led by Lindsay B. Yeates, the Australian Hypnotherapists Association (founded in 1949), the oldest hypnotism-oriented professional organization in Australia, instituted a peer-group accreditation system for full-time Australian professional hypnotherapists, the first of its kind in the world, which "accredit[ed] specific individuals on the basis of their actual demonstrated knowledge and clinical performance; instead of approving particular 'courses' or approving particular 'teaching institutions'" (Yeates, 1996, p.iv; 1999, p.xiv). The system was further revised in 1999.
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
