Taking on the challenge to walk 10,000 steps a day is a great decision for better health.
Ten thousand steps equates to about eight kilometres , or an hour and 40 minutes walking, depending on your stride length and walking speed. But that doesn’t mean you have to do it all in one walk. You will naturally accumulate steps through your day-to-day activities but to reach the 10,0000 step goal, you will need to do a 30 minute walk (or the equivalent in other exercise) as well.
Every little bit counts throughout the day — you could walk part of the way to work, take a stroll at lunchtime, have a walk-and-talk coffee meeting, walk to the supermarket instead of driving, or take the dog out for a play in the park in the evening.
