What moves the number

Its floor is very high: 8.8 MET even “slowly”, because there is no gentle way to jump. That makes it an excellent warm-up and a poor burning tool: ten real minutes, broken up by pauses, are not ten minutes of rope. Count the time the rope is actually turning.

Why this number is lower than elsewhere

The MET formula gives TOTAL expenditure during effort, rest included — an hour sitting down is already 1 MET. Most calculators display that gross figure. The problem: your basal metabolism is already counted in your daily calorie needs. Showing the gross number counts it twice.

We subtract the resting MET and report only what the effort cost ON TOP. Thirty minutes of walking gives roughly 100 kcal here, against 140 elsewhere. It is less flattering, and it is the only number that does not contradict itself when you step on the scale a month later.

It is also why these calories are never handed back to your food budget in the app: a workout is not a licence to eat.

Where the number comes from

A MET measures the cost of an activity relative to rest: 8 MET is eight times what a still body burns. The values used here come from the Compendium of Physical Activities (Ainsworth et al., 2011), the reference table of physical activity research.

Expenditure is then: (MET − 1) × 3.5 × weight in kg × minutes ÷ 200. Weight matters because you have to move it; duration matters more than anything else.

These are population estimates. Two people of the same weight doing the same effort can differ by 10 to 15 %: fitness, technique, temperature. Use these numbers to compare sessions with each other, not to balance a day to the calorie.

General, informational benchmarks based on published values validated on the general population. Real expenditure varies between two people with the same profile. These numbers do not replace a doctor or dietitian.
