This exercise calories per hour calculator estimates how much energy you burn during gentle, low-impact movement — from easy walking and relaxed cycling to yoga, Pilates, tai chi, and stretching. It uses the metabolic equivalent of task (MET) method, the same approach used in exercise science research, and adjusts the estimate to your body weight and actual session length.
Choose an activity, enter your weight and workout duration, and the calculator returns calories burned per hour and for the full session. The built-in quick-duration buttons and custom MET field let you tailor the estimate to your routine, whether that is a 30-minute dog walk, a 45-minute yoga class, or an hour of easy cycling.
No equipment or heart-rate monitor is needed — just a rough idea of your body weight and what you did. This makes it ideal for beginners, older adults, and anyone looking for realistic energy-expenditure numbers during moderate daily movement.

How This Calculator Works
This calculator uses the MET (metabolic equivalent of task) method, the standard way exercise physiologists estimate energy cost. The activity levels are based on the Compendium of Physical Activities. One MET equals your resting metabolic rate — the energy you burn sitting quietly. Gentle Hatha yoga scores about 2.5 METs, while brisk walking scores around 4.3 METs. Because 1 MET roughly equals 1 kcal per kilogram of body weight per hour, the formula becomes: kcal burned = MET × weight (kg) × session length (hours).
Example: A 70 kg person does 45 minutes of Hatha yoga at 2.5 MET. Hourly burn = 2.5 × 70 = 175 kcal/hr. Session burn = 175 × 0.75 = 131 kcal.
Step-by-Step Guide
- Enter your body weight and choose kg or lb.
- Select the activity closest to what you did.
- Set the session length using the number box or the quick duration buttons.
- If you know the exact MET for your activity, enter it in the custom MET field; it will override the activity selection.
- Press Calculate and read your total calories plus the per-hour breakdown.
For a closer look at specific short sessions, try the 25-minute walking calculator or the cycling MET calculator to compare different bike intensities.
Reference MET Values for Gentle Activities

| Stretching | 2.3 | 161 |
| Pilates | 3.0 | 210 |
| Tai Chi | 3.0 | 210 |
| Walking, easy | 2.8 | 196 |
| Walking, brisk | 4.3 | 301 |
| Cycling, very light | 4.0 | 280 |
| Cycling, leisure | 6.8 | 476 |
| Ballroom dance, slow | 3.0 | 210 |
| Golf, carrying clubs | 4.3 | 301 |
Tips for Making Gentle Movement Count
- Gentle exercise burns fewer calories per minute than intense exercise, so session length and consistency matter more than speed.
- Try a 15-minute easy walk after meals; a few shorter walks can add up to a similar total.
- Add short brisk intervals every few minutes to raise the average MET without making the session feel hard.
- Use a weekly total instead of a single session to stay motivated and see realistic progress.
Beginner tip: If a 10-minute gentle yoga routine feels challenging at first, log it anyway. The MET method still gives you a useful number, and consistency builds the habit.
Frequently Asked Questions
Why do my numbers look lower than what my fitness tracker says?
Tracker estimates often add resting calories to exercise calories, while this calculator reports net exercise cost in METs. It also uses a general population average; your actual burn depends on fitness, body composition, terrain, temperature, and movement efficiency.
Can I lose weight with yoga and walking?
Yes, if you maintain a calorie deficit overall. A 70 kg person burns about 175 kcal in 45 minutes of Hatha yoga or 196 kcal in 45 minutes of easy walking. Over a week, five such sessions add roughly 875–980 kcal — meaningful support for a modest deficit.
Should I log the per-hour or per-session number?
Log the session total, because that is what applies to your day. The per-hour value is useful for comparing activities side by side.
Accuracy Notes & Limitations
- MET values are population averages from the Compendium of Physical Activities, not exact physiology.
- Your body composition matters — muscle burns more energy than fat even at the same body weight.
- Terrain, weather, carrying weight, and technique change real calorie burn.
- Use this tool as a planning guide, not a medical prescription.
Note: If you have a heart condition, joint issues, or are new to exercise, speak with a healthcare provider before starting a new movement routine.
