How this is worked out
- Take the MET value for boxing from the 2024 Adult Compendium of Physical Activities: MET 8.5, the median of its 7 measured variations (MET 5.8–12.3).
- 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 8.5 × 3.5 × 70 ÷ 200 = 10.41 kcal/min 10.41 × 15 min = 156 kcal

A number this clean is a model. It does not know your gradient, your gear, the wind, or how hard you were actually trying.
