Walking is supposed to be one of the best forms of exercise so it makes sense to incorporate it into your day in as many ways as possible.
Walking to work is an obvious one. Not easy if you have a really long commute.
However everyone can manage a short walk at some point during the day, perhaps during a lunch break.
Think of all the wonderful fresh air you can get and all the lovely scenery you can enjoy,
So maybe give it a try this week.
