So for me, 10,000 steps is approximately 8km or 5 miles, a few websites seem to use the following figures to describe activity levels though I would dispute the highly active term as that should be higher in my mind

• Sedentary is less than 5,000 steps per day
• Low active is 5,000 to 7,499 steps per day
• Somewhat active is 7,500 to 9,999 steps per day
• Active is more than 10,000 steps per day
• Highly active is more than 12,500

Everyday after work I do a walk till I'm over 10,000, plus at least once a week I do a walk up in the hills (most of my city is flat). I have always enjoyed walking but let life get in the way, trying to make it a standard part of my day now
