How Many Calories Do You Burn On A Treadmill (With Calculator)

When it comes to finding out how many calories* you can burn on a treadmill, there are a number of different factors that come into play. We are going to take a look at how many calories a person weighing 125 pounds can burn in a 30-minute exercise session on a treadmill at different intensity levels. This will give you a relatively good idea of how many calories you can burn on a treadmill. But, keep in mind that these figures are estimates.

*The unit of measure commonly called a “calorie” is actually a “kilocalorie” – however “calorie” is so commonly used, we will use the shorter term here.

Walking On A Treadmill – Calories Burned

Walking at a slow pace at around 3.5 miles per hour can be considered to be a light-intensity workout on a treadmill. A person who weighs around 125 pounds and he or she walks on a treadmill at a slow and steady pace can expect to burn off around 125 calories in 30 minutes. A person weighing more than 125 pounds will burn more calories, depending on the weight, but it is not really effective to use a treadmill to work out for half an hour at light intensity. It does not affect the overall weight loss by a significant margin unless you give it at least an hour every day.

30 Minute Treadmill Workout – Calories Burned

Now, if you step up your game and use the treadmill to walk briskly for 30 minutes, you can burn more calories on a treadmill. Walking at 4.5 miles per hour at a steady pace will allow a person weighing 125 pounds to burn just over 200 calories in half an hour. The heavier the person, the more calories will be burned. While this is a major improvement than walking slowly, it is still not a significant fat burner and you should not expect it to affect your overall weight loss efforts by a huge margin.

Running On A Treadmill – Calories Burned

If you really pick up your pace and start running, you can enhance your weight loss efforts and bring the scale down a bit. For a person weighing 125 pounds and running steadily at around 5 miles per hour on the treadmill, an estimated 247 calories can be burned on the machine in half an hour. That is significantly a lot more than the time you would spend walking on the treadmill.

How to Maximize Calories Burned On A Treadmill

If you really want to push yourself and make the treadmill a useful tool to help you lose weight, you might want to take things up even higher than simply running. If you can use bursts of sprinting at 10 miles per hour throughout a 30-minute session with a few seconds gaps in between to burn a total of almost 500 calories per session.

Of course, the key is to be consistent in your workout efforts for losing weight using the treadmill. Make sure that you stick to either the medium or high-intensity workouts on your treadmill with the high-intensity interval sprints from time to time to maximize the number of calories you burn on a treadmill.
