Exercise does not have to be complicated. We almost always have access to somewhere to walk, and walking is a great activity. If you are going to walk and haven’t done so in a while start slowly. We recommend increasing the length of the walk by 10% per week maximum. If you have been walking and want to know what you can do to increase your intensity, speed up or add some stairs to your walk. Getting to a moderate to vigorous intensity during your walk requires you to be at a point where you are working so hard that you are feeling challenged and almost out of breath.
