1. Introduction

Body mass index, also known as BMI, is a heuristic proxy for estimating human body fat based on an individual's weight and height. On this study, the aim is to find out how the lack of exercise would affect the BMI of an individual. This research is important because it allows people to know that lack of exercise would cause a change in the BMI. Having high or low BMI increases health risks. This study impacts the society to think about exercising regularly because it might affect their health in the long run.

We have chosen this topic as we would like to find out more about how exercise affects our health. It is said that regular exercise helps in boosting the immune system and insulin sensitivity is decreased due to exercise (Home Remedies, 2009). This allows us to fulfill the requirements of the project task as the project task looks at the effect of not exercising, exercising and over-exercising, which is also what we would be doing.
It is possible to carry out and complete this project as there are many people in the neighbourhood to interview and to survey. The proposed course of action is logical and realistic as it can be completed with the help of students who would be willing to do our survey and with our hard work and group effort.

This task is fairly difficult as it is hard to get solid evidence and statistics easily. However, through surveys and interviews from outside, it is a challenge but not impossible.

To summarise some of the articles we read that might help us in our research, Both increased exercise capacity and BMI were associated with lower mortality in patients with an intermediate to high likelihood of CAD (Coronary Artery Disease) after controlling for confounding variables, supporting an inverse impact on BMI mortality.

Information/Knowledge that will be relevant to our research would be the amount of time people usually spend on exercising on average each day.

We will be obtaining this information from primary and secondary sources, depending on which one gives more reliable and useful information. Some alternatives that we have thought of would be to ask others for information or where can we find the information that we need (e.g. the Internet).

Some problems we anticipate while gathering my materials would be that the information that we can find is not entirely relevant to our project and that that is already the closest piece of information among all others that we have found.
