exercube
684 kcal / hour ExerCube burns approximately 684 calories per hour for a 70 kg (154 lb) adult, and 342 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 488 to 1,172 kcal.
It carries a MET value of 9.3 in the 2024 Adult Compendium of Physical Activities.
Calories burned exercube 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) | 122 | 244 | 366 | 488 | 732 |
| 60 kg (132 lb) | 146 | 293 | 439 | 586 | 879 |
| 70 kg (154 lb) | 171 | 342 | 513 | 684 | 1,025 |
| 80 kg (176 lb) | 195 | 391 | 586 | 781 | 1,172 |
| 90 kg (198 lb) | 220 | 439 | 659 | 879 | 1,318 |
| 100 kg (220 lb) | 244 | 488 | 732 | 977 | 1,465 |
| 110 kg (243 lb) | 269 | 537 | 806 | 1,074 | 1,611 |

What 684 calories an hour actually means
At MET 9.3, exercube counts as very vigorous activity — it uses about 9.3 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 11 kcal per minute, or 684 kcal across a full hour.
Within conditioning exercise, that ranks 9th of 53 activities by energy cost, a little below kettle bell swings (MET 9.8) and above high intensity interval exercise (MET 9).
Put differently: one hour of exercube costs about the same energy as 140 minutes of ordinary walking.
On the food side, a plain bagel (about 245 kcal) takes roughly 22 minutes of exercube 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 exercube burn per hour?
About 684 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 9.3. A 90 kg adult burns closer to 879 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of exercube burn?
Roughly 342 kcal at 70 kg, 293 kcal at 60 kg and 488 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of exercube?
9.3. One MET is the energy you use sitting quietly, so MET 9.3 means 9.3 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.
