489 kcal / hour Health club exercise burns approximately 489 calories per hour for a 70 kg (154 lb) adult, and 244 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 349 to 838 kcal.
It carries a MET value of 6.65 in the 2024 Adult Compendium of Physical Activities, which lists 2 measured variations of this activity from MET 5.5 to 7.8.
Calories burned health club exercise 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) | 87 | 175 | 262 | 349 | 524 |
| 60 kg (132 lb) | 105 | 209 | 314 | 419 | 628 |
| 70 kg (154 lb) | 122 | 244 | 367 | 489 | 733 |
| 80 kg (176 lb) | 140 | 279 | 419 | 559 | 838 |
| 90 kg (198 lb) | 157 | 314 | 471 | 628 | 943 |
| 100 kg (220 lb) | 175 | 349 | 524 | 698 | 1,047 |

Every official intensity of health club exercise
The Compendium lists 2 separate health club exercise entries, each with its own measured MET value — from 5.5 to 7.8. 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 |
|---|---|---|---|---|
| Health club exercise (general) | 5.5 | 404 | 520 | — |
| conditioning classes | 7.8 | 573 | 737 | — |
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 489 calories an hour actually means
At MET 6.65, health club exercise counts as vigorous activity — it uses about 6.65 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 8 kcal per minute, or 489 kcal across a full hour.
Within conditioning exercise, that ranks 22th of 53 activities by energy cost, a little below teaching exercise classes (MET 6.8) and above aerobic dance (MET 6.4).
Put differently: one hour of health club exercise costs about the same energy as 100 minutes of ordinary walking.
On the food side, a chocolate bar (about 235 kcal) takes roughly 29 minutes of health club exercise 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 health club exercise burn per hour?
About 489 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 6.65. A 90 kg adult burns closer to 628 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of health club exercise burn?
Roughly 244 kcal at 70 kg, 209 kcal at 60 kg and 349 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of health club exercise?
6.65, taken as the median of the 2 health club exercise entries in the 2024 Adult Compendium, which range from 5.5 to 7.8 depending on intensity. One MET is the energy you use sitting quietly, so MET 6.65 means 6.65 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.
