Key Takeaways
- The Compendium provides 7 distinct boxing MET values ranging from 5.5 (bag, general) to 12.3 (in-ring, general).[1]
- A 30-minute sparring session (7.8 MET) estimates approximately 287 kcal for a 70 kg person.[3]
- In-ring boxing (12.3 MET) is one of the highest-MET activities in the entire Compendium.[1]
- The round-based mode accounts for rest periods (1.0 MET) between work rounds for more accurate session estimates.
- These are informational estimates for personal journaling. Individual results vary with technique and conditioning.

| Training Type | MET | 55 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|---|
| Punching Bag (General) | 5.5 | 159 | 202 | 245 | 289 |
| Punching Bag (60 b/min) | 7 | 202 | 257 | 312 | 368 |
| Sparring | 7.8 | 225 | 287 | 348 | 410 |
| Punching Bag (120 b/min) | 8.5 | 245 | 312 | 379 | 446 |
| Simulated Round (Exercise) | 9.3 | 269 | 342 | 415 | 488 |
| Punching Bag (180 b/min) | 10.8 | 312 | 397 | 482 | 567 |
| In-Ring (General) | 12.3 | 355 | 452 | 549 | 646 |
How the Estimate Works
The calculator uses the standard MET formula with training-type MET values from the Compendium:[1]
Calories = (MET × 3.5 × Wt_kg × Duration_min) ÷ 200
Time-based mode applies the training MET for the full duration. Round-based mode separates work rounds (training MET) from rest periods (1.0 resting MET) and sums both for the total estimate.
Training Types Explained
Punching Bag, General (5.5 MET)
General bag work at mixed pace. Includes a variety of punches with natural rest between combinations (Compendium code 15110).[1]
Sparring (7.8 MET)
Controlled partner sparring. Combines offensive and defensive movement with sustained intensity (code 15120).[1]
Simulated Round (9.3 MET)
Structured round simulation for fitness boxing. Mimics fight-pace effort without a partner (code 15125).[1]
In-Ring, General (12.3 MET)
Full-intensity ring work or competitive bout. Among the highest-MET activities in the entire Compendium (code 15100).[1]
Bag, 120 b/min (8.5 MET)
Fast-tempo bag work at approximately 2 punches per second. Sustained effort requiring significant aerobic output (code 15115).[1]
Bag, 180 b/min (10.8 MET)
Very fast tempo bag work at approximately 3 punches per second. Near-maximal effort for short bursts (code 15118).[1]
Round Structure Guide
Boxing training traditionally uses a round-based structure. Common configurations include:
- Standard (3 min / 1 min rest): The traditional boxing round. Used in professional and amateur bouts.
- Fitness boxing (2 min / 30 sec rest): Shorter rounds with minimal rest. Common in group fitness classes.
- HIIT rounds (1 min / 15 sec rest): High-intensity interval format for maximum sustained effort.
The round-based calculator accounts for both work calories (at training MET) and rest calories (at 1.0 resting MET) to provide a complete session estimate.
