Indoor cycling, also known as spinning, has become one of the most popular cardiovascular workouts worldwide. Whether you attend a high-energy group class or spin solo on your stationary bike at home, understanding how many calories you burn during your workout is crucial for tracking fitness progress, weight management, and overall health planning.

1. What Is Indoor Cycling?
Indoor cycling involves riding a stationary bike, often in a class setting called “spinning,” where instructors lead interval, resistance, and cadence drills to simulate outdoor cycling conditions. The controlled environment allows for year-round training and precise intensity control using resistance knobs or power metrics.
2. Understanding Calories and Energy Expenditure
A calorie is a unit of energy. When we talk about burning calories, we usually refer to kilocalories (kcal), the energy our body consumes to perform activities including exercise.
Energy expenditure during exercise depends on:
- The intensity of the activity
- Duration of the workout
- Body weight and composition
- Fitness level
Indoor cycling’s calorie burn varies widely, influenced by these factors and how vigorously you pedal.
3. Metabolic Equivalent of Task (MET) and Indoor Cycling
A practical and widely used method to estimate calories burned is based on METs (Metabolic Equivalent of Task). One MET equals the energy cost while sitting quietly (approximately 1 kcal/kg/hour).
How METs work for indoor cycling:
- Different cycling intensities correspond to specific MET values.
- Calories burned can be estimated using:
Calories burned=MET value×weight (kg)×duration (hours)Calories burned=MET value×weight (kg)×duration (hours)
Table 1: MET Values for Different Exercise Bike Intensities
| Intensity Level | MET Value | Description |
|---|---|---|
| Low intensity | 3 | Light effort, easy pedaling |
| Moderate | 5.5 | Steady pace, moderate resistance |
| High | 7 | Vigorous effort |
| Very High | 11 | Race pace, sprint intervals |
4. How Many Calories Does Indoor Cycling Burn?
Calorie burn varies by weight and intensity. Below is an illustrative table based on moderate to vigorous effort for 1 hour.
Table 2: Estimated Calories Burned Cycling for 1 Hour Based on Body Weight
| Body Weight (lbs) | Calories Burned (Light effort) | Calories Burned (Moderate/Vigorous) |
|---|---|---|
| 100 | 218 | 436 |
| 125 | 273 | 545 |
| 150 | 327 | 654 |
| 175 | 382 | 763 |
| 200 | 436 | 872 |
| 225 | 491 | 981 |
| 250 | 546 | 1090 |
5. Factors That Influence Indoor Cycling Calorie Burn
- Body Weight: Heavier individuals burn more calories due to greater energy demands.
- Workout Intensity: Higher resistance, cadence, or sprint intervals increase burn.
- Duration: Longer sessions equal more calories burned.
- Fitness Level: More conditioned athletes may burn fewer calories for the same effort.
- Age and Gender: Metabolism differences affect calorie use.
- Heart Rate: Higher heart rate zones correspond with greater calorie expenditure.
- Bike Setup and Efficiency: Proper bike fit optimizes energy use.
6. Methods to Calculate Calories Burned on Indoor Bikes
6.1 METs Method (Simpler, General Estimate)
Calories/min=MET×3.5×Weight (kg)200Calories/min=200MET×3.5×Weight (kg)
Multiply by total minutes for full session.
Table 3: Calories Burned Per Minute by Weight and Intensity Using METs
| Weight (kg) | Low (3 METs) | Moderate (5.5 METs) | High (7 METs) | Very High (11 METs) |
|---|---|---|---|---|
| 50 | 2.6 | 4.7 | 6.0 | 9.4 |
| 60 | 3.1 | 5.3 | 7.0 | 11.5 |
| 75 | 3.9 | 6.8 | 9.0 | 14.2 |
| 90 | 4.7 | 8.1 | 10.8 | 17.0 |
| 100 | 5.2 | 9.2 | 12.3 | 19.4 |
6.2 Karvonen Method (Heart Rate Based, More Accurate)
For men:Calories/min=[(Age×0.2017)−(Weight×0.09036)+(HR×0.6309)−55.0969]×Time (min)4.184Calories/min=4.184[(Age×0.2017)−(Weight×0.09036)+(HR×0.6309)−55.0969]×Time (min)
For women:Calories/min=[(Age×0.074)−(Weight×0.05741)+(HR×0.4472)−20.4022]×Time (min)4.184Calories/min=4.184[(Age×0.074)−(Weight×0.05741)+(HR×0.4472)−20.4022]×Time (min)
This method integrates actual heart rate and personal parameters for precise calculation.

| Effort Level | MET Value | 30 min | 60 min | 90 min |
|---|---|---|---|---|
| Low | 3 | 41 | 82 | 123 |
| Moderate | 5.5 | 75 | 150 | 225 |
| High | 7 | 95 | 190 | 285 |
| Very High | 11 | 150 | 300 | 450 |
8. How to Maximize Calories Burned on Indoor Cycling
- Increase resistance to challenge your muscles more.
- Incorporate intervals: alternate between sprint and recovery.
- Maintain higher cadence (rpm) during high-intensity phases.
- Extend workout duration gradually.
- Combine cycling with strength training and proper nutrition.
- Monitor heart rate zones to train at maximal fat-burning rates.
9. Using Heart Rate and Power to Improve Accuracy
Modern indoor bikes and wearables provide power output (watts) and heart rate data, which can be plugged into more precise calorie expenditure formulas:Calories=METs×weight (kg)×duration (hours)Calories=METs×weight (kg)×duration (hours)
Where METs correlate to watts produced (e.g., 100 watts ≈ 6 METs).
Using power meters on indoor trainers combined with your weight yields tailored estimates (RunBundle, 2025).
10. Summary & Practical Advice
Indoor cycling burns calories in proportion to your body weight, exercise intensity, and workout duration. Using MET values offers a practical estimation method, while heart rate-based calculations provide higher precision.
Typical calorie burns span:
- Light effort: ~200–300 kcal/hr
- Moderate effort: ~400–600 kcal/hr
- High effort: ~600–900+ kcal/hr
For effective weight loss or fitness gains, supplement cycling with a balanced diet, consistent routine, and gradual progression in difficulty.
