How Many Calories Does Rucking Burn?
What’s rucking, you might ask.
The answer is that rucking is walking at a tempo of 3.5 to 4 miles per hour with a weighted backpack.
Because of this powerful combination of cardio and resistance training, rucking burns more calories than walking.
As a result, rucking can transform your body from fat to fit, fast.
Just go out and ruck for 30 minutes to an hour a day carrying a 20-pound ruck plate and see what happens.
This new fitness trend is called rucking, because in the United States Armed forces, a backpack is called a ruck pack.
To calculate the number of rucking calories burned per hour, use the following three simple steps.

3 Simple Steps to Calculate Calories Burned Rucking
1. MET – Metabolic Equivalent of a Task
The first step to calculate how many calories you burn with any physical activity is to know the METs.
The Metabolic Equivalent of a Task (METs) will tell you how many calories you burn per hour of exercise per one kilogram of body weight.
According to the Compendium of Physical Activities, the METs for backpacking on level terrain with a 21 to 42-pound load is 7.0.
While walking up hills with the same weight is 8.3. The METs of Rucking on a flat surface with a 21 to 42 lb weight is approximately 7.0.
Remember that baseline number.
(The METs will change based on how much weight you add to your ruck pack and the incline of hills you are climbing.)
| 1993 Compendium | 2000 Compendium | 2011 Compendium | Walking | |||
|---|---|---|---|---|---|---|
| Codes | METs | Codes | METs | Codes | METs | Description |
| 17010 | 7.0 | 17010 | 7.0 | 17010 | 7.0 | backpacking (Taylor Code 050) |
2. Determine your Weight in Kilograms
The second step to calculate how many calories you burn rucking is to find your weight in kilograms.
All you need to do is divide your weight in pounds by 2.2.
If you weigh 195.7 pounds, the average weight of a man in the U.S.¹, divide this number by 2.2, which leaves you with 88.95 kilograms.
Once you know your weight in kilograms, you can now move to the formula in the next step.
3. Use the METs Formula to Measure Calories Burned Rucking
The METs formula is:
- Rucking calories burned (or any other physical activity) = METs x weight in kg x time in hours.
If you do not work out for an hour, then express this number as .5 for 30 minutes or .25 for a 15-minute workout.
A proper ruck march for fitness is 30 minutes to an hour.
Using our example of a 180 pound (81.8kg) individual, we can plug in our numbers to the formula.
- Calories burned = METs of 7.0 for rucking x 88.95kg x time (1 hour or .5 for 30 minutes or .25 for 15 minutes)
- 7.0 x 88.95 x 1 = 622.65 calories burned rucking (assuming an hour long ruck march).
- If you did a ruck march carrying a 35-pound weight in 30 minutes, then your formula would be 7.0 x 88.95 x .5 = 311.325 calories burned rucking.
Compare this to the average calories burned walking at 3.5 mph for an hour, which consumes approximately half the numbers above.

Rucking Benefits
Rucking is a fundamental component of U.S. Special Forces training to build a soldier’s strength and endurance.
Rucking benefits for soldiers and civilians include:
- Improved posture
- Increases bone density to help prevent osteoporosis
- Strengthens joints, muscles, and ligaments
- Builds up your cardiorespiratory endurance
- Active resistance training to increase your strength with the rucksack on your back
- Cardio, conditioning, and strength training benefits at the same time
- Rucking is a perfect application of the overload principle for weight loss and muscle gain in action
- Running is tough on your knees and joints, whereas rucking is not.
- The British Journal of Sports Medicine ² reports that long-distance runners have an injury rate of 20 to 70 percent.
- This high rate of injuries when running is because your knees absorb a shock between seven and twelve times your bodyweight.
- The artofmanliness.com reports the number of calories burned rucking for an average man weighing 200 pounds is between 450 calories and 585 calories per hour.
