How this is worked out
- Take the MET value for circuit training from the 2024 Adult Compendium of Physical Activities: MET 5.5, the median of its 4 measured variations (MET 3.5–7.5).
- Convert MET to a rate using the ACSM relationship: multiply by 3.5, then by body mass in kilograms, then divide by 200. That gives kilocalories per minute.
- Multiply the rate by the number of minutes actually spent.
- Round to whole kilocalories. Nothing else is applied — no age factor, no sex factor, no proprietary adjustment, because the underlying data does not support one.
kcal/min = MET × 3.5 × mass(kg) ÷ 200 kcal = kcal/min × minutes 5.5 × 3.5 × 70 ÷ 200 = 6.74 kcal/min 6.74 × 90 min = 606 kcal
