When the colder weather arrives it seems so easy to set down and put your feet up, keeping up a regime of jogging during the cold winter evenings can be difficult, so what better solution than to transfer to jogging on a treadmill. However jogging indoors can’t burn the same number of calories unless all the conditions were equal which of course they can’t be.
Why not? Because of the differing environmental changes, wind resistance being number one on the list. Terrain will vary also, with inclines that require more energy to be expended.
The more work the body does the more calories it will burn. With non-competitive joggers the calorie difference will be minor as they tend to slow down when the going gets tougher; such as jogging up hill or against the wind.
One way to make your indoor workout physically demanding enough to match your outdoor, one is to first monitor your heart rate during the outdoor run. When on the treadmill increase the speed or the incline, or both, to make your heart rate match.
Another way is to avoid holding on to the handrails of the treadmill as this will only make the workout easier and reduce your calorie burn.
