Maximizing Calorie Burn: The Ultimate Guide to Rucking Efficiency

Ever wondered how much calories you’re burning while rucking? You’re not alone. It’s a common question among fitness enthusiasts and outdoor adventurers alike. Rucking, or walking with a loaded backpack, is not just a military exercise anymore. It’s become a popular fitness trend, and for good reason.

This low-impact exercise is a great way to torch calories, tone muscles, and improve cardiovascular health. But just how many calories does rucking burn? Well, that depends on several factors. Factors like your weight, the weight of your backpack, and the intensity of your ruck can all play a part.

What is Rucking?

You might be asking yourself, what’s rucking? Rucking, in its simplest terms, is walking while carrying a centered load, commonly in the form of a backpack. This increasingly popular exercise is more than just a casual stroll with a pack; it’s a dynamic, challenging exercise that is as versatile as it’s beneficial.

Rucking originated from the military, where soldiers would be tasked with carrying loads of up to 100 pounds across long distances. However, don’t worry if you’re not a seasoned weightlifter – you don’t need to carry that much weight to start rucking. In fact, you can start with a backpack filled with whatever weight you feel comfortable carrying. As you grow stronger, you slowly increase the weight of your pack.

One often forgotten but significant aspect of rucking is that it’s a low stress, high reward form of exercise. While activities like running can cause wear-and-tear due to the high-impact nature of the exercise, rucking is relatively low-impact. The added weight of the backpack makes your body work harder, increasing the number of calories burned without adding unnecessary strain on your joints.

Rucking’s key point of differentiation lies in its adaptability and flexibility. Whether you’re walking your dog or hitting the mountain trails, you can incorporate rucking into nearly every walking-based activity. You set the pace, distance, and weight according to your fitness level and goals.

The Benefits of Rucking

In a world where fitness routines can often seem monotonous, rucking offers a refreshing change. It’s essentially walking with a weighted pack. Though rooted in military routines, rucking has gained massive popularity amongst fitness enthusiasts for the multifold benefits it offers.

Firstly, you might be wondering about how many calories rucking can help you burn. A key benefit of rucking is, it can burn up to three times as many calories as walking without additional weight. Depending on the pace, distance, and weight, rucking can help you burn anywhere from 300 to 600 calories per hour. It’s an impressive calorie burn, especially considering it’s a low-impact workout that doesn’t put excessive strain on your joints.

Another significant benefit of rucking is that it strengthens your cardiovascular system. The added weight increases your heart rate, which in turn improves cardiovascular health over time. You’d also notice improvements in your stamina and endurance levels with regular rucking.

Rucking also provides an excellent workout for your upper body. When you carry a weight on your back, it works your shoulders, traps, and back muscles, leading to increased strength and better posture. It’s not just about walking; rucking adds a new dimension to your fitness regime by incorporating strength training.

Lastly, rucking is highly customizable. You can control the pace, distance, and weight, which allows you to adapt the exercise according to your fitness levels and goals. You’re not hitched to someone else’s pace or stuck in a gym setting.

Not to forget, introducing something different to your exercise routine can keep you motivated and interested. And the fact that you can do rucking anywhere – in the city, park, or even the mountains – adds more fun and variety to your workout regime.

Thus, whether you’re a fitness novice or a seasoned gym-goer, adding rucking into your workout routine can be beneficial for you.

Factors that Affect Calorie Burn

Surprisingly, rucking burns more calories than walking without a pack. Yet, you might be wondering, ‘how much more’? Interestingly, there isn’t a one-size-fits-all answer. Several factors come into play affecting how many calories you burn during a rucking session. Let’s dive into some of these critical factors.

Weight of Your Ruck

First and foremost, the weight of your pack significantly impacts the number of calories you burn while rucking. Generally, the heavier your load, the greater the calorie burn. Adding more weight increases resistance which, in turn, intensifies your workout.

Rucking Duration

Simply put, more time spent rucking equals more calories burned. Much like any other form of exercise, the longer the training session, the higher the caloric expenditure. If you’re aiming for a lengthy, calorie-torching ruck, make sure you properly hydrate and pace yourself.

Rucking Speed

Although rucking is essentially a walking exercise, your speed will affect your calorie burn. Faster rucking leads to increasing your heart rate which subsequently ups the calorie burn. Nonetheless, remember to balance speed with the weight of your ruck to avoid injury and have a productive rucking session.


Lastly, consider the terrain on which you’re rucking. A flat, smooth surface ruck might not burn as many calories as tackling hills or uneven grounds. Choosing challenging terrains can up the intensity and provide a full-body workout apart from the core muscle group recruitment.

Now that you’re acquainted with the factors that play a pivotal role in determining calorie burn during rucking, you can strategically plan your rucking sessions. Experimenting with these parameters will not only help you achieve your fitness goals but also keep your workouts diverse and enjoyable.

How to Calculate Calorie Burn while Rucking

An efficient way to gauge your calorie burn during rucking is by tracking four primary factors —the weight of the load you’re carrying, the length of your session, the speed at which you move, and the difficulty of your terrain.

Load Weight

A fundamental factor in rucking is the weight you carry. The heavier your pack, the more calories you’ll burn. It’s simple physics. Your body has to work harder to haul a heavier load, hence consuming more energy or calories.


If you’re keen on burning more calories, be prepared to commit more time. A longer ruck aids in burning a higher number of calories, as it keeps your metabolism ramped up for an extended period. However, remember to pace yourself—you don’t want to risk overexertion.


Speed is a crucial determinant too. If you ruck at a faster pace, your heart rate will soar, leading to increased calorie expenditure. But again, maintaining a balanced pace is key. The last thing you’d want is an injury to set back your fitness regime.

Terrain Challenge

Lastly, the strenoutness of the terrain rocks up the intensity of your workout. Rough, inclined, or chaotic terrains compel your body to work harder, thus increasing the calorie burn.

You might be wondering, how do you quantify these factors?

Numerous online calorie calculators can assist you in estimating the calories burnt during your rucking sessions. All you have to do is input the necessary details like weight of your pack, session duration, speed, and in some cases, type of terrain. The calculator will then provide a pretty accurate estimate of calories burnt.

To give you a clearer picture, consider a rucking session where you’re carrying a 50lbs pack, rucking for two hours at a speed of 3.5 mph on a moderate terrain:

Pack WeightRucking TimeSpeedTerrain
50lbs2 hours3.5mphModerate

Upon entering these details into a calorie calculator, you’d find that your burn rate could be somewhere in the range of 800-1000 calories. Of course, each person’s body composition and fitness level could alter these outcomes.

Tips for Maximizing Calorie Burn during Rucking

You’ve understood the factors that affect calorie burn in rucking. Now, it’s time to discuss how you can maximize this burn. Note that the overarching aim isn’t just to burn calories. It’s also about enhancing your fitness levels, boosting endurance, and even enjoying the great outdoors.

Tip 1: Vary Your Load
The weight of your pack is a significant factor. It’s simple – the heavier your load, the greater the calories you’ll burn. Start with a comfortable weight, perhaps 10% of your body weight. Gradually increase it over time. This way, your body has the chance to adapt, and you reduce the risk of injury.

Tip 2: Increase Your Speed
Calorie burn also depends on the speed at which you move. Aim to maintain a brisk pace. When you’re comfortable, challenge yourself by attempting quick bursts of speed within your session.

Tip 3: Mix Up the Terrain
Try to tackle different terrains. This will not only challenge your body but also ramp up the intensity of your workout, potentially burning more calories. From mountain trails to sandy beaches, varying terrains offer a mix of physical challenges and views that can invigorate your rucking sessions.

Tip 4: Extend Your Session
Duration matters too. Longer rucking sessions result in greater calorie burn. But don’t rush to hit the trail for hours on end. Rather, extend your session gradually, adding small increments to ensure that you don’t overdo it.

Always be mindful of your body’s signals. Every person’s fitness level varies, and what works well for one person might not be the same for another. Listen to your body and adjust your routine accordingly.

Tip 5: Use an Online Calculator
Online calorie calculators can be a helpful guide. Input the weight of your pack, the duration of your session, the speed, and the difficulty of your terrain to estimate your calorie burn. This can help you track your progress, set achievable goals, and stay motivated.

Remember, consistency is key. Regular rucking can lead to improved physical health, stronger muscles, and, yes, higher calorie burn. So pack up, lace up, hit the trail, and revel in the benefits of rucking.


So, you’ve learned how to amp up your calorie burn with rucking. By tweaking the weight of your pack, picking up the pace, and switching up your surroundings, you can boost your burn. Remember, it’s all about listening to your body and staying consistent. Online calorie calculators can be a handy tool for keeping track of your progress and setting those all-important goals. With regular rucking, you’re not just burning calories – you’re also taking strides towards better overall health. Now it’s time to strap on that pack and start rucking your way to a fitter, healthier you.
