Measure calorie burn with workout and health inputs. See estimates from time, distance, and METs. Export clean reports for tracking progress across training days.
| Example | Activity | Weight | Duration | Intensity | Estimated Calories |
|---|---|---|---|---|---|
| Sample 1 | Treadmill | 75 kg | 45 min | Moderate | 337 kcal |
| Sample 2 | Elliptical | 68 kg | 30 min | Vigorous | 242 kcal |
| Sample 3 | Cycling | 82 kg | 60 min | Moderate | 519 kcal |
| Sample 4 | HIIT | 70 kg | 25 min | Vigorous | 343 kcal |
1. MET calories: Calories = MET × weight in kg × duration in hours.
2. Heart rate method: The calculator uses sex-based heart rate equations when heart rate is provided.
3. Blended estimate: Final exercise calories combine the MET estimate with the heart rate estimate when both are available.
4. Net active calories: Net calories = gross calories − resting calories burned during the same workout time.
5. BMR: The calculator uses Katch-McArdle when body fat is entered. Otherwise it uses Mifflin-St Jeor.
This calculator estimates calories burned during many common gym sessions. It works well for treadmill, cycling, rowing, elliptical, stair climbing, HIIT, and strength circuits. It is useful when you want more than a simple number. It also shows net active calories, resting calories, BMI, pace, and session load.
Many basic tools only use time and body weight. This one goes further. You can add distance, speed, incline, resistance, heart rate, body fat, and a manual MET value. That gives you more control. It also blends different methods when more data is available.
The first part uses METs. MET stands for metabolic equivalent. It connects exercise intensity with energy use. The second part uses heart rate if you enter it. This can improve the estimate for cardio sessions. The calculator then adjusts the result by activity type and your chosen adjustment factor.
Gross calories include all calories burned during the session. Net active calories remove the energy you would have burned anyway at rest. Many people prefer net calories when comparing workouts. It can give a cleaner picture of effort.
Try to enter body weight carefully. Duration also matters a lot. Heart rate helps during steady cardio. Distance and speed help for walking, running, and cycling. Incline and resistance help for machine work. Body fat is optional, but it improves the daily burn estimate through a lean-mass based BMR formula.
Start with gross calories. Then review net calories and calories per minute. Pace and speed help you compare sessions. Session load helps you judge effort over time. Export options make it easier to save your report, share it, or build your own progress log.
No. It works for cardio and circuit-style training. You can choose treadmill, cycling, rowing, HIIT, elliptical, stair climbing, walking, running, or strength circuit sessions.
Gross calories are the total estimated burn during exercise. Net calories subtract the calories your body would likely burn at rest during the same amount of time.
Enter it when you have a realistic average heart rate. It is helpful for cardio sessions. If you leave it blank, the calculator still works with MET-based estimation.
It lets you nudge the result up or down. Use it if your machine readings are usually higher or lower than your wearable or lab-tested estimates.
Yes. Manual MET is useful when you already know the activity MET from a reliable source. When you enter it, that value takes priority.
BMI is included as a quick body-size reference. It is not the calorie formula itself. It simply adds useful context to the session summary.
Yes. If you know your body fat percentage, the tool can estimate BMR using lean mass. That helps when displaying resting calories and daily energy needs.
Yes. Use the CSV option for spreadsheets and logs. Use the PDF option for a clean report you can store, print, or share.
