Bad weather and no treadmill doesn't mean you have to give up on your workout. It doesn't take much skill or space to run in place.
How many calories you'll burn depends on your size and your effort level, but it'll definitely be more than you'll burn sitting on the couch.
How many calories you burn depends on how much you weigh, how long you run and how vigorously you run. A person who weighs 150 pounds going at an average effort for 15 minutes burns about 119 calories, but a 200-pound person burns about 159 calories.
Compared to Outdoor Running
You can only go so “fast” when you're running in place. You'll burn more calories when you go outside because you have to propel yourself forward, push off the ground, use your arms more and fight wind resistance. For example, the same 150-pound person going 5 mph on an outdoor (or treadmill) run for 15 minutes burns 144 calories or 196 at 7 mph.
Burn More Calories
The surest way to burn calories when working out is to vary and gradually increase the intensity of your workout, according to University of Mexico, a tactic that is hard to do while running in place. Instead of jogging in place, consider doing a set of calisthenics, such as jumping jacks, burpees and push-ups.
In 15 minutes, you'll burn 137 calories if you go at an intense effort.
