rock or mountain climbing
588 kcal / hour Rock or mountain climbing burns approximately 588 calories per hour for a 70 kg (154 lb) adult, and 294 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 420 to 1,008 kcal.
It carries a MET value of 8 in the 2024 Adult Compendium of Physical Activities.
Calories burned rock or mountain climbing 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) | 105 | 210 | 315 | 420 | 630 |
| 60 kg (132 lb) | 126 | 252 | 378 | 504 | 756 |
| 70 kg (154 lb) | 147 | 294 | 441 | 588 | 882 |
| 80 kg (176 lb) | 168 | 336 | 504 | 672 | 1,008 |

What 588 calories an hour actually means
At MET 8, rock or mountain climbing counts as vigorous activity — it uses about 8 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 10 kcal per minute, or 588 kcal across a full hour.
Within sports, that ranks 27th of 91 activities by energy cost, a little below soccer (MET 8.25) and above fencing (MET 7.9).
Put differently: one hour of rock or mountain climbing costs about the same energy as 120 minutes of ordinary walking.
On the food side, a medium banana (about 105 kcal) takes roughly 11 minutes of rock or mountain climbing 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 rock or mountain climbing burn per hour?
About 588 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 8. A 90 kg adult burns closer to 756 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of rock or mountain climbing burn?
Roughly 294 kcal at 70 kg, 252 kcal at 60 kg and 420 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of rock or mountain climbing?
8. One MET is the energy you use sitting quietly, so MET 8 means 8 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.
