Calories burned
circuit training
404 kcal / hour Circuit training burns approximately 404 calories per hour for a 70 kg (154 lb) adult, and 202 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 289 to 693 kcal.
It carries a MET value of 5.5 in the 2024 Adult Compendium of Physical Activities, which lists 4 measured variations of this activity from MET 3.5 to 7.5.
Calories burned circuit training by body weight
Energy cost scales with the mass you move, so body weight changes the answer more than anything else.
| Body weight | 15 min | 30 min | 45 min | 60 min | 90 min |
|---|---|---|---|---|---|
| 50 kg (110 lb) | 72 | 144 | 217 | 289 | 433 |
| 60 kg (132 lb) | 87 | 173 | 260 | 347 | 520 |
| 70 kg (154 lb) | 101 | 202 | 303 | 404 | 606 |
| 80 kg (176 lb) | 116 | 231 | 347 | 462 | 693 |
| 90 kg (198 lb) | 130 | 260 | 390 | 520 | 780 |
| 100 kg (220 lb) | 144 | 289 | 433 | 578 | 866 |
| 110 kg (243 lb) | 159 | 318 | 476 | 635 | 953 |

Every official intensity of circuit training
The Compendium lists 4 separate circuit training entries, each with its own measured MET value — from 3.5 to 7.5. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.
| Variation | MET | kcal/hr at 70 kg | kcal/hr at 90 kg | Code |
|---|---|---|---|---|
| light effort | 3.5 | 257 | 331 | 02035 |
| moderate effort | 5 | 368 | 473 | 02045 |
| body weight exercises | 6 | 441 | 567 | 02032 |
| including kettlebells, some aerobic movement with minimal rest, general, vigorous intensity | 7.5 | 551 | 709 | 02049 |
Codes are 2024 Adult Compendium activity codes. A dash means the code could not be read unambiguously from the published table, so it is left blank rather than guessed — the MET value and description are unaffected.
What 404 calories an hour actually means
At MET 5.5, circuit training counts as moderate activity — it uses about 5.5 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 7 kcal per minute, or 404 kcal across a full hour.
Within conditioning exercise, that ranks 32th of 53 activities by energy cost, a little below resistance training (MET 5.8) and above water aerobics (MET 5.4).
Put differently: one hour of circuit training costs about the same energy as 83 minutes of ordinary walking.
On the food side, a can of cola (about 140 kcal) takes roughly 21 minutes of circuit training to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.
Questions
How many calories does circuit training burn per hour?
About 404 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 5.5. A 90 kg adult burns closer to 520 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of circuit training burn?
Roughly 202 kcal at 70 kg, 173 kcal at 60 kg and 289 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of circuit training?
5.5, taken as the median of the 4 circuit training entries in the 2024 Adult Compendium, which range from 3.5 to 7.5 depending on intensity. One MET is the energy you use sitting quietly, so MET 5.5 means 5.5 times that rate.
Is this an exact number of calories?
No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.
