Which gives the greater calorie burn – running outside or running on a treadmill?
When running outside, your body is being propelled forward by your legs, which is not the case when running on a treadmill. In addition, the constant variations in terrain outside mean your body is constantly having to work to deal with these variations. Therefore, running outside burns more calories as a general rule. It should be noted that on a treadmill it is possible to set the pace and incline and create for yourself a more challenging workout than going for a run outside but, all things being equal, outdoor running burns more calories!
