Over the course of any given day, some activities will naturally be more demanding than others. As an example, stair climbing is one of the more challenging activities that most of us encounter in our everyday lives and requires significantly greater effort than walking uphill. Walking uphill requires significantly greater effort than walking on a flat surface and each of those activities requires significantly greater effort than sitting on the couch watching TV.
