Run Baby Run

Running is a healthy exercise, provided that you do it by the rules. If you are just starting your training, you should begin by mild sessions, for example 2.5 minutes walk then 30 seconds run. Week by week you can gradually increase the running interval, but be careful with overstraining.
This application will help you set your times, and prompt you at each interval, so you can just focus on your course.
