10,000 steps are less than one kilometer, but not so by much. Your shop-around- the-corner is possibly much further. And it takes only ten or fifteen minutes to reach the shop.

For numbers over one thousand (1000), a comma (,) is necessary.

Then why does an the average person do much less steps than 10,000 steps for 1440 day minutes of the day? I mean with all his work, ways travel to work and to home, and the meetings with friends he has. His average day’s activity usually doesn’t exceed 5000 steps (2-3 two to three campaigns to the shop-around-the- corner and back).

"I'm an average person." But the way you are using it here is a little more specific, so "the" is required.

I also have these walk only 5000 steps when it’s too very cold or enormously hot outdoors (that’s almost several months of an a year in Moscow). But when the wheather weather is more or less good, I take my pedometer, pleer iPOD(?) and go to the nearest park, or just to the center of the city.

I changed "too cold" to "very cold." If it's "too cold," then you wouldn't go walking at all.

By "pleer," do you mean to say "iPOD or MP3 player"?

And I walk and listen to my pleer iPOD(?) (usually audiobooks than music). It gives me enough activity (much more than the recommended 10,000 steps), and I manage to listen to several chapters of an audiobook. Last time I combined walking and developing my English listening skills by listening VOA radio broadcasts. It helps a lot.

I like to listen to audiobooks too when I'm walking. It gives me the incentive to get out and walk, since I want to know what happens next in the story.

I used to do gymnastics, sufficient exercises to accumulate meet a normal level of activity, but my weak willpower doesn’t agree to do with doing something for a long time that it doesn’t want to do. It likes tennis and bicycle bicycling, and I’m allowed to play tennis as long as I want. But I haven’t found something anything more appropriate for my daily routine than simple simply walking around the park after a cup of morning tea.

weak willpower / doesn't agree with / conscious mind (that thinks it's a great idea to do something for a long time)

I enjoy walking, but when I'm feeling especially energetic I go hiking in the nearby hills. If I had a mountain bike like some of the guys I meet on the trail, I would go mountain biking. I wonder if that's possible where you live.
