Colley's Invention can be used by fitness enthusiasts to provide a means of walking, running, or jogging in the home during periods of inclement weather. The unit would not only provide a means of working the muscles in the legs but would help elevate an individual's heart and respiratory rates and increase circulation, thus providing an effective cardiovascular workout, which would help boost metabolism and burn calories. Consistent use of the machine could potentially lead to stronger, well-toned legs, weight loss, increased self-esteem, and a healthier lifestyle.
