Rooted in Hindu philosophy, yoga seeks to join the mind, body and spirit. But many classes these days make the practice more about the workout than the mental health benefits. If burning kilojoules is what you're really after, why not save that money you'd spend at a studio and try going for a walk, instead? 

Whether you need a break from your mat or just prefer changing scenery, these three walking working will burn just as many kilojoules as your go-to hatha yoga classes - and offer a different peace of mind.
