With Fly_ShuttleRun you can train your physical condition by using your mobile phone as a timer for the Shuttle Run Test. Start to run when you hear the beeps and try to reach the other end of the track before the beeps sound again.
Of course, the time between two beeps slightly decreases every time. When you don't make it to the other side in time, press the Stop button. You'll then see your average speed and the level you reached.
