Let's walk! How? Where? How? How to control?

Let's walk! Decision is made. But it is important to understand how it can be usefully and safely implemented. How to start walking? How to walk effectively? Where is the best place to go? How much do you need to walk to get a health and training effect? How to control your body during training walking? About this and about some details in this video.
The video chat is for EVERYONE.
Sincerely, Yuri Tsukanov.
