100 Mountain Climbers Calories: Exactly How Much Do 100 Reps Burn?
Find out how many calories 100 mountain climbers burn based on your body weight and pace. Includes calorie tables, time estimates, and a comparison with other 100-rep challenges.
"100 mountain climbers" has become a popular fitness challenge — searched for by people doing tabata workouts, HIIT circuits, and 30-day challenges alike. But how many calories does this benchmark actually burn?
The answer depends on your body weight and how fast you perform them. This guide gives you a precise calorie breakdown for 100 mountain climbers across different weights and paces, plus context for how it compares with other popular 100-rep challenges.
How Many Calories Do 100 Mountain Climbers Burn?
At moderate pace (approximately 70 knee drives per minute), 100 mountain climbers takes about 1 minute 26 seconds and burns:
| Body Weight | Calories Burned (100 reps, moderate pace) |
|---|---|
| 55 kg (121 lbs) | 10 kcal |
| 65 kg (143 lbs) | 12 kcal |
| 70 kg (154 lbs) | 13 kcal |
| 75 kg (165 lbs) | 14 kcal |
| 80 kg (176 lbs) | 15 kcal |
| 90 kg (198 lbs) | 17 kcal |
| 100 kg (220 lbs) | 19 kcal |
These estimates use the MET 8.0 value for vigorous calisthenics from the Compendium of Physical Activities, combined with a realistic 70 reps/min pace.

How Pace Changes the Calorie Count
Pace affects both time and MET value, so faster reps burn more calories per minute even though you complete 100 reps faster:
| Pace | Reps/Min | Time for 100 Reps | MET | Calories (70 kg) |
|---|---|---|---|---|
| Slow / Controlled | 40 | 2 min 30 sec | 6.0 | 10.5 kcal |
| Moderate | 70 | 1 min 26 sec | 8.0 | 13.3 kcal |
| Fast / HIIT | 100 | 1 min | 10.0 | 11.7 kcal |
Interesting finding: Moderate pace actually burns the most calories for 100 reps because the combination of intensity and time is optimal. Fast pace completes the 100 reps so quickly that the higher MET doesn't compensate for the shortened duration.
What Counts as a "Rep" in Mountain Climbers?
This is a common source of confusion. In standard mountain climbers:
- Each knee drive = 1 rep (most common counting method)
- Alternatively, some trainers count left + right = 1 rep — which would make "100 reps" actually 200 knee drives
This guide uses the convention of 1 knee drive = 1 rep, which is the most widely used approach in HIIT and challenge workouts. If your trainer counts both legs as a single rep, double the calories listed above.
100 Mountain Climbers in a HIIT Circuit
In practice, most people do 100 mountain climbers as part of a HIIT interval, not as a single continuous set. Common formats:
Tabata Format (20s on / 10s off)
- Each 20-second burst at fast pace: ~30–35 reps
- You'd need approximately 3 rounds to reach 100 reps
- Total time including rest: ~90 seconds
- Calories burned (active time only, 70 kg): ~12 kcal
Standard HIIT (30s on / 15s off)
- Each 30-second burst at moderate pace: ~35 reps
- 3 rounds = ~105 reps, close to the target
- Calories burned (active time only, 70 kg): ~14 kcal
Cumulative Calorie Potential: Daily 100-Rep Challenge
If you do 100 mountain climbers every day for 30 days:
| Body Weight | Daily Calories | 30-Day Total |
|---|---|---|
| 60 kg | ~11 kcal | ~330 kcal |
| 70 kg | ~13 kcal | ~390 kcal |
| 80 kg | ~15 kcal | ~450 kcal |
| 90 kg | ~17 kcal | ~510 kcal |
That's roughly equivalent to one extra snack burned per day. While 100 reps alone won't create dramatic fat loss, the daily habit builds fitness and contributes meaningfully to an active lifestyle when combined with other exercise.
100 Mountain Climbers vs. Other 100-Rep Challenges
| Exercise | Reps | Time (moderate pace) | Calories (70 kg) |
|---|---|---|---|
| Mountain Climbers | 100 | ~1.4 min | 13 kcal |
| Push-ups | 100 | ~6.7 min | 35 kcal |
| Burpees | 100 | ~16.7 min | 130 kcal |
| Jumping Jacks | 100 | ~3.3 min | 26 kcal |
| Lunges | 100 | ~5 min | 29 kcal |
| Sit-ups | 100 | ~5 min | 23 kcal |
Mountain climbers have the lowest calorie burn per 100 reps simply because they're performed so quickly. But in calories per minute, they rank among the highest-intensity bodyweight exercises available.
How to Burn More Calories in Your Mountain Climber Sets
To maximize calorie burn during mountain climbers:
- Increase duration rather than just rep count. 5 minutes of continuous mountain climbers burns far more than two quick sets of 100.
- Use a HIIT protocol. Alternating between maximum-intensity bursts and brief rest periods keeps heart rate elevated throughout the session.
- Add a cross-body variation. Mountain climbers with a twist (bringing knee to opposite elbow) increase core engagement and slightly raise the metabolic cost.
- Combine with planks. Transitioning from static plank holds into mountain climbers creates a richer cardiovascular stimulus.
- Reduce rest between sets. Shorter rest periods maintain a higher average heart rate, increasing total calorie burn for the session.
Is 100 Mountain Climbers a Good Workout Goal?
As a standalone goal, 100 reps is a reasonable benchmark for beginners and intermediates. Here's how to frame it:
- Beginner: 4 sets of 25 with 60-second rest
- Intermediate: 2 sets of 50 with 30-second rest
- Advanced: 1 continuous set of 100 at maximum pace
For serious calorie burn, build toward longer continuous bouts — 5 to 10 minutes at moderate pace — rather than focusing on rep milestones. See our guide on 10 Minutes of Mountain Climbers Calories for what that effort can achieve.
