As hinted in the title to this paper and on the introductory part, this is an advanced experimental clinical psychology paper that employs single-subject approach of the broad qualitative research method to investigate the notion that exercising leads to reduction of weight.

Again, as explained above and as the name implies single-subject approach allows the study off body/ behavior changes on one person, a family or a one group of people and indicate whether changes a person makes over a given time frame are as a result of the ongoing pattern or if they are real change in behavior. Single-subject approach can lead to a conclusion whether the change experienced is too big to have been accidentally achieved and therefore make it easy for positive inferences to be made based on the effectiveness of the intervention applied.

[Cherry, (1999)] Of late my body weight has been increasing tremendously, now my weight oscillates between 77 and 80 kilograms, a phenomenon which I attribute to my lack of indulgence in weight loosing activities such as performance of strenuous physical fitness exercises; it is this realization that led me to carry out an advanced experimental clinical psychology qualitative study on whether physical exercises can lead to weight loss, with myself as the subject.

Specific Research Question(s) 1. What happens if one fails to perform regular body exercises for along time? 2. Do regular body exercises lead to weight loss? Hypotheses Various research studies have been carried out on the issue of body weight and regular body exercises, however, their conclusions are always too general i. e. not realistic to some extreme cases.

Individual body differences always prevail in determining the weight trends of people, I therefore hypothesize that; my lack of performing regular body exercises is the main cause of my consistently increasing body weight; that regular exercises leads to burning of extra fat in the body; that over exercising may be dangerous to the body and therefore fail to reduce body weight; that for one to loose weight s/he indulge in numerous types of physical exercises and not one, and; that exercise alone can not constitute to an effective method of reducing of body weight.

Literature Review Physical exercises referred to as any body activities that help to maintain physical fitness and the overall health of the body are performed for various reasons that may include; cardiovascular system muscle strengthening, perfecting athletic skills, weight loss or maintenance, boosting of the immune system, prevention of childhood obesity, and general diseases prevention. [Donatelle & Rebecca (2005)] It is also known that physical exercises help to improve mental health and the prevention of depression.

Physical exercises can be grouped into three categories depending on the specific parts of the body that will be involved e. g. aerobic exercises that involves running, walking, hiking, swimming, cycling, rowing, or playing tennis all which are focused on increasing cardiovascular endurance; anaerobic that involves sprinting, weight training, and functional training all which are aimed at increasing short-term muscle strength, and; flexibility exercises such as stretching to improve the range of muscles.

A proper combination and balancing of these exercises can lead to the achievement of the above mentioned benefits. [Hardman & Stensel (2009)] However, not everybody equally benefits from physical exercises whereas some responds to exercises by tremendously reducing their excess weight some will moderately loose their weight while others will never get a benefit from training. [Kolata, Gina (Feb. 12, 2002)] It is also known that over exercising may lead to body complications such as muscle tear, depression, stroke or various circulation complications. [Alexander (1998)]
