Stretching calorie chart
Estimated kcal for stretching (MET 2.3) by session length and body weight. Values are rounded estimates.
| Duration | 50 kg | 60 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|---|
| 10 min | 19 | 23 | 27 | 33 | 38 |
| 15 min | 29 | 35 | 40 | 49 | 57 |
| 20 min | 38 | 46 | 54 | 65 | 77 |
| 30 min | 57 | 69 | 81 | 98 | 115 |
| 45 min | 86 | 104 | 121 | 147 | 172 |
| 1 h | 115 | 138 | 161 | 195 | 230 |
| 1.5 h | 172 | 207 | 242 | 293 | 345 |
Imperial check: 154 lb ≈ 70 kg · 187 lb ≈ 85 kg · 220 lb ≈ 100 kg.
About this estimate
Stretching carries a MET of 2.3(light intensity) in the Compendium of Physical Activities — the research standard for energy-cost data (source database, see also our full methodology). The calculator uses:
calories = MET × weight (kg) × hours
So for a 70 kg person, one hour of stretching costs about161 kcal. Effort matters: going harder, adding hills, carrying load or rushing intervals all push the real number up; breaks and easy pacing pull it down.
How to burn more
- Add intervals — 1 minute hard, 2 minutes easy — to raise average intensity.
- Extend the session gradually; an extra 10 minutes adds ~27 kcal at 70 kg.
- Combine with a second activity — see the compare tray in the calculator above.
- Keep non-exercise movement high on rest days (walking, stairs, chores).
Estimate only — not medical advice. Real-world burn depends on fitness, body composition, age, weather and terrain.

How many calories does stretching burn in an hour?
About 161 kcal for a 70 kg person at MET 2.3. Double the time roughly doubles the burn, assuming steady effort throughout.
What is the MET of stretching?
The MET (metabolic equivalent of task) of stretching is 2.3 — light intensity. The formula is: calories = MET × weight(kg) × hours. Example at 70 kg: 2.3 × 70 × 1 h = 161 kcal.
