Bridge is a low-impact, bodyweight exercise that strengthens the glutes, hamstrings, and core while keeping your spine in a neutral position. At vigorous intensity, you perform the movement with a fast tempo, minimal rest between reps, and a strong glute squeeze at the top. This calculator estimates the calories you burn during a bridge workout based on your body weight, exercise duration, and your chosen intensity level.
Whether you're a beginner building a home routine, a fitness enthusiast tracking daily energy expenditure, or a coach planning a conditioning session, this tool gives you a quick, evidence-based estimate. It uses the standard metabolic equivalent (MET) values from the Compendium of Physical Activities, so you can trust the numbers for planning and progress tracking.
Enter your weight, select your intensity, and set the duration to see your estimated calories burned, plus a breakdown of the calculation. You can also use the quick-fill presets to see how different body weights and session lengths affect your results.

How to Use This Tool
Using the bridge calorie calculator is straightforward. Start by entering your body weight in kilograms or pounds, then set the duration of your bridge workout in minutes or hours. Choose your intensity level: Moderate corresponds to a steady, controlled tempo with short rests, while Vigorous represents a fast-paced, high-effort session with minimal rest between sets. The calculator applies the appropriate MET value and returns an estimated calorie burn.
For quick comparisons, use the preset buttons to load common scenarios like a 60 kg person doing 20 minutes or an 80 kg person doing 45 minutes. After calculating, you'll see the total calories and a breakdown showing the MET value, your weight in kilograms, and the duration in hours, along with the formula used.
How It Works
The estimate is based on the metabolic equivalent of task (MET) system, which expresses the energy cost of physical activities as a multiple of resting metabolic rate. One MET is roughly the energy you burn while sitting quietly. The Compendium of Physical Activities assigns a MET value to various exercises; for calisthenics and bodyweight exercises performed at vigorous effort, a MET of 6.0 is commonly used, while moderate effort is around 3.5.
The formula is: Calories burned = MET × 3.5 × weight (kg) ÷ 200 × duration (hours). The factor 3.5 represents the approximate oxygen consumption in milliliters per kilogram per minute at rest, and dividing by 200 converts the result into kilocalories per minute. This is the same approach used in many fitness trackers and exercise science textbooks.
For example, a 70 kg person doing vigorous bridges for 30 minutes would burn: 6.0 × 3.5 × 70 ÷ 200 × 0.5 = 36.75 kcal. That may seem modest, but bridge workouts are often combined with other exercises in a circuit, and the cumulative burn adds up.
Worked Examples
Example 1: A 65 kg woman performs vigorous bridges for 25 minutes. Calories = 6.0 × 3.5 × 65 ÷ 200 × (25/60) = 28.4 kcal.
Example 2: A 90 kg man does moderate bridges for 40 minutes. Calories = 3.5 × 3.5 × 90 ÷ 200 × (40/60) = 36.75 kcal.
Example 3: A 55 kg beginner does vigorous bridges for 15 minutes. Calories = 6.0 × 3.5 × 55 ÷ 200 × 0.25 = 14.4 kcal.
Tips & Best Practices
- Focus on form: keep your feet hip-width apart, press through your heels, and squeeze your glutes at the top of the movement.
- To increase intensity, slow down the lowering phase, add a pause at the top, or use a resistance band around your thighs.
- Combine bridges with other glute exercises like clamshells, donkey kicks, and squats for a balanced lower-body routine.
- Track your workouts consistently to see how your calorie burn changes as you get stronger and can maintain a higher tempo.
Factors Affecting Accuracy
The MET values are averages based on population studies, so individual results vary. Your actual calorie burn depends on your muscle mass, fitness level, age, and how strictly you maintain the vigorous tempo. The calculator assumes continuous effort; if you take long rests between sets, your effective MET will be lower. For the most accurate tracking, consider using a heart rate monitor or a fitness tracker that accounts for your personal physiology.
Frequently Asked Questions
Is bridge a good exercise for weight loss? Bridge primarily strengthens muscles, but it contributes to overall daily energy expenditure. For weight loss, combine it with a calorie-controlled diet and other cardiovascular activities.
Can I do bridges every day? Yes, bridges are low-impact and generally safe for daily practice, but listen to your body. If you feel lower back discomfort, reduce the range of motion or consult a professional.
How many calories does a 10-minute bridge session burn? For a 70 kg person at vigorous intensity, about 12.25 kcal. It's a small amount, but it adds up when included in a longer workout.
What is the difference between moderate and vigorous intensity? Moderate intensity means you can talk but not sing, while vigorous intensity means you can only say a few words without pausing for breath. In bridge, vigorous also implies a faster rep tempo and shorter rest.
