Whether you are walking around the block, training for a race, or performing structured strength workouts, every movement requires energy. Calculating the calories you burn during different exercises can help you coordinate your nutrition, manage your body weight, and track your fitness progress.
To estimate the energy cost of physical activities, exercise physiologists use a metric called MET, which stands for **Metabolic Equivalent of Task**.
One MET is defined as the energy your body expends while sitting quietly at rest (equivalent to burning roughly 1 calorie per kilogram of body weight per hour). Activities with higher intensities have higher MET values. For example, light walking has a MET value of around 3, while running at a moderate pace has a MET value of approximately 10, meaning it burns ten times more energy than sitting still.
To see how your baseline resting metabolic burn compares, check out our basal metabolic rate planner or check our full daily calorie energy planner.
The actual number of calories you burn depends on several personal variables: - Body Weight: A heavier person requires more energy to move their body across a distance, resulting in a higher calorie burn for the same activity compared to a lighter person. - Exercise Intensity: Working harder (such as sprinting versus jogging) increases your heart rate and energy demand. - Workout Duration: The longer you perform an activity, the more total energy you expend.
If you want to track your speed and pacing during running or walking sessions, use our pace calculator.
Here are some typical MET values for popular forms of physical activity: - Slow Walking (3 mph): 3.3 METs - Bicycling (moderate effort): 8.0 METs - Running (6 mph or 10 min/mile): 9.8 METs - Circuit Training (weights): 6.0 METs - Swimming (moderate laps): 5.8 METs
To check if your weight falls within standard clinical height guidelines, try our Body Mass Index classifier or view our healthy weight range finder.
Suppose a person weighing 70 kg (154 lbs) goes for a 45-minute moderate run (MET value of 10).
To calculate the calories burned: - Calories = MET × Weight (kg) × Duration (hours) - Duration = 45 minutes / 60 = 0.75 hours - Calories = 10 × 70 × 0.75 = 525 calories burned.
This run burns approximately 525 calories, which you can factor into your daily meal planning. If you need to perform additional math calculations, try our everyday daily math helper.
While cardiovascular exercises (like running or cycling) typically burn more calories during the session itself, resistance training offers unique long-term energy benefits. Strength workouts build lean body tissue, which is more metabolically active than fat tissue.
Additionally, high-intensity workouts cause EPOC (Excess Post-Exercise Oxygen Consumption), commonly known as the "afterburn effect," where your body continues to burn calories at an elevated rate for hours after you finish training. To evaluate your lean body tissue ratio, visit our lean body mass estimator or try our body fat percentage calculator.
For successful weight management, it is helpful to look at your total energy balance over the entire day rather than just single workouts. Combining your resting metabolic rate with your physical activity levels gives you your total daily expenditure.
To calculate your total daily burn based on lifestyle and movement, use our total daily energy expenditure solver. To coordinate your calorie output with macronutrient goals, check out our macronutrient ratios helper or explore our protein calculator and fat intake guide.
