Cool down

We need to do a 5 minutes cool down after each power walking session, so we make sure that the blood is circulated and the waste products will be faster eliminated. This way you will recover quicker, and have a good feeling of  'job done' at the end.
 Repeat a few time 30 seconds of slow jogging followed by walking other 30 seconds...and then reduce the intensity and do a calm walk for a few minutes.
