Collapsing Frame Concept for a Manually Powered Portable Treadmill

In the United States, entire generations are spending increasing amounts of time in settings that do not allow for healthy amounts of physical activity. These settings, such as schools, workplaces, and public spaces, often encourage people to sit in a stationary position for long periods of time. This has led to an increase in the prevalence of obesity, heart disease, and diabetes in the United States. In order to help combat the harmful effects of this sedentary lifestyle, this report proposes a portable, manually powered fitness device that can be used in a variety of settings. The device will achieve portability through its low weight and its ability to decrease its overall length for ease of storage and transportation. This project is a continuation of previous work completed as part of a project for MEMS 411: Senior Design at Washington University in St. Louis completed by Faizan Khan, Christopher Wendtt, and Nolan Knapp. This report also makes use of previous work done on the project by David Wolshire as part of an independent study
