Have you ever attempted to get fit and lead a more healthy and active lifestyle? Have you tried working out, but quit because it was too difficult, you did not have the time, or you simply could not stick to your diet plan? The President’s Council on Fitness, Sports, and Nutrition states that only one in three adults receive the recommended weekly amount of physical exercise. There are many reasons why people do not exercise regularly, which may also be linked to increases in stress. According to a report by the Global Organization for Stress in 2011, stress levels are rising in the workplace, with six out of ten workers reporting significant increases. Focusing on the psychology of fitness in my project, I seek to determine if a correlation exists between increased physical activity and decreased stress levels. By collecting data though a series of surveys given to clients at Underground Fitness, a center for personal training, I will examine whether fitness and dieting can lead to a healthier lifestyle over time. If there is a correlation between physical exercise and decreased stress levels, I intend to share the results with friends, family, potential fitness trainers or doctors, giving the general populace a way to deal with everyday stress.
