The purpose of this research study is to determine if participation in a fifteen week introductory exercise regimen using the NuStep by sedentary adults diagnosed with Type 1 or Type 2 diabetes will affect exercise adherence and lifestyle adjustment. This study will examine if using the NuStep encourages participants to seek other modes and facilitates interest in exercise. Age, gender, weight, height, waist-to-hip ratio, heart rate, blood pressure, 6-minute walk test, and A1C will be recorded pre, mid-point, and post-test. During each NuStep exercise session heart rate, blood pressure, blood glucose level, oxygen saturation, METs, and the Borg rate of perceived exertion will be monitored.
