Calories burned
bench step class
573 kcal / hour Bench step class burns approximately 573 calories per hour for a 70 kg (154 lb) adult, and 287 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 410 to 983 kcal.
It carries a MET value of 7.8 in the 2024 Adult Compendium of Physical Activities.
Calories burned bench step class 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) | 102 | 205 | 307 | 410 | 614 |
| 60 kg (132 lb) | 123 | 246 | 369 | 491 | 737 |
| 70 kg (154 lb) | 143 | 287 | 430 | 573 | 860 |
| 80 kg (176 lb) | 164 | 328 | 491 | 655 | 983 |
| 90 kg (198 lb) | 184 | 369 | 553 | 737 | 1,106 |
| 100 kg (220 lb) | 205 | 410 | 614 | 819 | 1,229 |
| 110 kg (243 lb) | 225 | 450 | 676 | 901 | 1,351 |

What 573 calories an hour actually means
At MET 7.8, bench step class counts as vigorous activity — it uses about 7.8 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 10 kcal per minute, or 573 kcal across a full hour.
Within conditioning exercise, that ranks 16th of 53 activities by energy cost, a little below virtual reality fitness (MET 7.9) and above calisthenics (MET 7.5).
Put differently: one hour of bench step class costs about the same energy as 117 minutes of ordinary walking.
On the food side, a chocolate bar (about 235 kcal) takes roughly 25 minutes of bench step class 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 bench step class burn per hour?
About 573 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 7.8. A 90 kg adult burns closer to 737 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of bench step class burn?
Roughly 287 kcal at 70 kg, 246 kcal at 60 kg and 410 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of bench step class?
7.8. One MET is the energy you use sitting quietly, so MET 7.8 means 7.8 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.
