Key Takeaways
- Mountain climbers are classified as vigorous calisthenics (MET 8.0 at moderate pace) in the Compendium, engaging core, shoulders, hip flexors, and quads simultaneously.[1]
- Pace strongly affects intensity: slow/controlled at MET 6.0 vs. fast/HIIT at MET 10.0 — a 67% increase in energy expenditure.[2]
- Vigorous sessions may produce an additional 6–15% afterburn (EPOC) above the in-session calorie count.[3]
How the Calculation Works
The calculator uses pace-specific MET values with the standard formula:
kcal = MET × weight(kg) × hours
In rep-count mode, duration is auto-calculated: minutes = totalReps ÷ repsPerMinute.
For similar bodyweight exercises, try the High Knees Calculator or the Jogging in Place Calculator.
Limitations and Important Notes
- MET values are based on calisthenics research; individual calorie expenditure varies with form, body composition, and fitness level.
- Rep-to-time conversion assumes consistent pace throughout the set.
