And there is no better start than walking and you don't need any special equipment to get you going ,well it until you decide to go over hill and dale .
To get the maximum health benefits from walking you need to do about 10,000 steps a day as your target. Making small changes will have a culminate effect taking the stairs instead if the lift , my husband does this ( as his work lift is always breaking down!) and where possibke walking to walk.
Set yourself a goal to move every 30 minutes honestly if you out your mind to it ,this can work as it only takes 3 weeks to form a habit. You can keep track of your progress with a pedometer ( this vary in price) or you can download a pedometer app these range from paying for or free .
If you need inspiration about where to walk there are plenty of sites like Geocaching which encompass history and excercise (some are free and some you have to pay for. )
For general walking there are plenty of sites that allow you to plan routes , print out guides and find walking groups. And with skies like this why wouldn't you want to get out of there?
