well yeah, obviously. If you work harder in the same amount of time you will burn more, for sure. The main reason why I even bothered with this is because a lot of people that I know want to lose weight and have better cardio but they erroneously believe that they have to be out there running like crazy in order to do that. If they have enough time, and can just go for a walk and burn the same amount, that is something that can motivate them to get out there and do something. The jogging can come later once their bodies are more used to it.
