⚠️ Important Exercise Notice

This calories burned calculator provides estimates based on average metabolic rates. Individual results may vary based on fitness level, body composition, age, and other factors. Consult healthcare professionals before starting new exercise programs, especially if you have medical conditions.

Understanding Calories Burned

Comprehensive guide to exercise calorie expenditure, MET values, and factors affecting calories burned during physical activities.

🔥

MET (Metabolic Equivalent)

MET represents the ratio of working metabolic rate to resting metabolic rate. One MET equals the energy cost of sitting quietly, approximately 3.5 mL of oxygen per kg of body weight per minute.

⚖️

Body Weight Impact

Heavier individuals burn more calories during the same activity because their bodies require more energy to move the additional mass. A 200-pound person burns significantly more calories than a 120-pound person.

⏱️

Duration & Intensity

Both exercise duration and intensity affect total calories burned. Higher intensity activities have higher MET values, while longer durations increase total calorie expenditure proportionally.

🏃

Activity Types

Different activities have different MET values. Running at 8 mph has a MET of 11.5, while walking at 3 mph has a MET of 3.5. Sports and high-intensity activities generally burn more calories.

💪

Fitness Level Effect

More fit individuals may burn fewer calories doing the same activity due to improved efficiency. However, they can typically sustain higher intensities for longer periods, potentially burning more total calories.

📊

Calculation Formula

Calories = (MET × body weight in kg × time in hours). This formula, based on research studies, provides standardized estimates for calorie expenditure across various activities.

Frequently Asked Questions

Everything you need to know about calculating calories burned, exercise intensity, and using this tool for your fitness goals.

How can I increase calories burned during exercise?

+
Increase exercise intensity, duration, or frequency. Add resistance training to build muscle mass. Try interval training (HIIT). Choose activities with higher MET values. Maintain consistency and gradually progress your workout intensity.
