When it comes to Pokemon GO, there's one unavoidable fact: Sooner or later, you're going to have to do some walking.
Yes, you can get it in the car and drive around to different Gyms to avoid using the old shoe leather express, but some exercise simply can't be avoided. For example, the game is smart enough to know when you're in a car versus traveling by foot, so driving the 10 km to hatch the Pokemon egg isn't going to work.
Then again, some additional exercise is never a bad thing, and Niantic and Nintendo should be commended for getting people off their couches and roaming around outside. Now the next step is to see how that additional physical activity is paying off for you.
