Exercise Calorie Calculator – Track Your Burn and Maximize Results

Meet Alex. He’s 29, weighs 75 kg, and has recently started exercising regularly. After his first cardio session, he wondered:

"How many calories did I actually burn? Did that 45-minute run make a difference? Could I eat that post-workout snack or still stay on track?"

This confusion is common — and it’s exactly why the Exercise Calorie Calculator exists. With just a few inputs, it tells you how many calories you burn for any activity, helping you make smarter choices.

What is the Exercise Calorie Calculator?

This calculator is a tool that estimates the energy you burn during exercise based on:

• Exercise type – Running, cycling, swimming, yoga, weightlifting, etc.
  
• Your weight – Heavier bodies burn more calories for the same activity.
  
• Duration – How long you exercise in minutes.
  
• Intensity level – Light, moderate, or vigorous effort.
  

The calculator gives you Calories Burned, so you can see your actual energy expenditure.

Formula for Calories Burned

The calculator is based on MET values (Metabolic Equivalent of Task), which is a standard way to measure energy expenditure:

Calories Burned = MET × Weight (kg) × Duration (hours)

Where:

• MET is a value representing the intensity of the activity.
  
• Weight is your body weight in kilograms.
  
• Duration is exercise time in hours.
  

Example:

• Alex runs at 8 km/h → MET = 8.3
  
• Weight = 75 kg
  
• Duration = 45 minutes → 0.75 hours
  

Calories Burned = 8.3 × 75 × 0.75 ≈ 466 calories

So his 45-minute run burns roughly 466 calories.

2. Enter your weight – Use kilograms for the most accurate calculation.
   
3. Add duration – How many minutes you exercised.
   
4. Choose intensity level – Light (easy), Moderate (comfortable effort), or Vigorous (hard effort).
   
5. Press calculate – Instantly see your calories burned.
   
6. Interpret results – Compare with daily goals, nutrition intake, or adjust your next workout.
