About this estimate

Spin class carries a MET of 8.5(vigorous 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 spin class costs about595 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 ~99 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 spin class burn in an hour?

About 595 kcal for a 70 kg person at MET 8.5. Double the time roughly doubles the burn, assuming steady effort throughout.

What is the MET of spin class?

The MET (metabolic equivalent of task) of spin class is 8.5 — vigorous intensity. The formula is: calories = MET × weight(kg) × hours. Example at 70 kg: 8.5 × 70 × 1 h = 595 kcal.
