Walking has taken over fitness in 2026, and if you’ve been following along with trends like Japanese interval walking or walking yoga, you already know that a simple walk can be a legitimate workout. But there’s one walking variation that takes things to an entirely different level: rucking.
Rucking — walking with a weighted backpack — started as a military training staple and has exploded into the mainstream. NPR recently called it “an exceedingly practical fitness trend that might stick around.” And unlike most viral fitness trends, rucking is backed by decades of military research and a growing body of peer-reviewed science.
Here’s everything you need to know to start rucking safely and get the most out of every weighted step.
What Is Rucking?
Rucking is simply walking with weight on your back. The term comes from “rucksack” — military slang for a backpack. Soldiers have used loaded marches to build endurance and mental toughness for centuries, often carrying 50-70 pounds over long distances.
The civilian version is far more approachable. Most recreational ruckers carry 10-30 pounds in a backpack and walk 2-5 miles at a brisk pace. It’s the rare workout that simultaneously builds cardiovascular endurance, strengthens your legs and core, and burns significantly more calories than regular walking — all without the joint impact of running.
Think of it as the middle ground between a casual walk and a gym session. You get outdoors, you move your body, and the added weight does the heavy lifting (literally) of turning a simple walk into a full-body strength and cardio workout.
Why Rucking Burns So Many Calories
The science behind rucking’s calorie burn comes from the Pandolf Equation, developed by the U.S. Army Research Institute of Environmental Medicine. This model, refined over decades, accounts for body weight, pack weight, speed, and terrain to calculate the metabolic cost of loaded walking.
The numbers are compelling: carrying just 20% of your body weight roughly doubles the energy cost compared to walking unloaded at the same pace. At 30% of body weight, you can triple the calorie burn. For a 170-pound person rucking with a 25-pound pack at a brisk pace, that translates to roughly 400-500 calories per hour — compared to about 200 for a regular walk.
Recent research suggests the original Pandolf equation actually underestimates calorie expenditure by 12-33%, particularly at higher loads and faster speeds. So you may be burning even more than the formula predicts.
The Benefits of Rucking
Rucking’s appeal goes well beyond calorie burn. Here’s what the research and expert consensus point to:
Cardiovascular Fitness Without the Impact
Rucking keeps your heart rate in the aerobic “Zone 2” sweet spot — the intensity range that builds endurance, improves metabolic health, and supports longevity. Unlike running, which generates 2-3x your body weight in ground reaction forces with every stride, rucking keeps one foot on the ground at all times. That means serious cardio benefits with a fraction of the joint stress.
Full-Body Strength Building
The pack’s downward pull forces your posterior chain — glutes, hamstrings, back muscles, and core — to work constantly to keep you upright and moving forward. A study published in the Journal of Athletic Training found that loaded walking significantly increases ground reaction forces and muscular activation in the lower extremities. Over time, this builds functional strength that translates directly to everyday life.
Better Posture
Carrying weight on your back forces you to engage your core and pull your shoulders back. Do it consistently and you’ll notice improvements in posture, especially if you spend most of your day sitting. The constant engagement of your stabilizer muscles creates a natural “posture correction” effect that many ruckers report as one of the first noticeable benefits.
Bone Density
Weight-bearing exercise is one of the most effective ways to maintain and build bone density. Rucking amplifies the bone-loading stimulus of walking by adding external weight, making it a potentially valuable tool for people concerned about osteoporosis — particularly as they age.
Mental Clarity and Stress Relief
There’s something about carrying weight outdoors that forces you into the present moment. Many ruckers describe it as a form of moving meditation — the physical challenge quiets mental noise in a way that a casual stroll doesn’t. Plus, the outdoor exposure and rhythmic nature of walking both have well-documented stress-reduction benefits.
How to Start Rucking: A Beginner’s Guide
The beauty of rucking is its simplicity. Here’s how to get started without overcomplicating things:
Choose Your Weight
Start with 10% of your body weight. For a 160-pound person, that’s about 16 pounds. If you’ve never rucked before, even 10 pounds will feel like a meaningful increase. You can always add more once your body adapts — most experts recommend increasing by no more than 5 pounds every 2-3 weeks.
Don’t overthink the equipment at first. A regular backpack loaded with books, water bottles, or a sandbag works fine. If you want to invest in proper gear, ruck plates (flat weights designed for backpacks) sit high and close to your back, which keeps your center of gravity stable and protects your posture.
Plan Your First Ruck
Keep it short and simple:
Distance: 1-2 miles
Pace: 15-20 minutes per mile (brisk walking pace)
Terrain: Flat sidewalks or paved paths
Duration: 20-30 minutes total
Focus on maintaining good posture throughout — chest up, shoulders back, core engaged. Swing your arms naturally and take comfortable strides. If you feel your form breaking down, the weight is too heavy or you’ve gone too far. Dial it back.
Build Your Routine
Once you’re comfortable with 2 miles at your starting weight, you have two progression paths:
Add distance first. Increase by half a mile per week until you’re comfortably rucking 3-4 miles.
Then add weight. Once you’re solid at your target distance, add 5 pounds and drop the distance back slightly while your body adjusts.
Aim to ruck 2-3 times per week with at least one rest day between sessions. Your shoulders, feet, and back need recovery time — especially in the first month.
Rucking vs. Other Walking Workouts
How does rucking stack up against the other walking trends of 2026?
Rucking vs. Japanese Walking: Japanese interval walking alternates between fast and slow walking to build cardiovascular fitness. Rucking adds external load instead of speed variation. Both are 30-minute-friendly. If you want cardio-focused training, Japanese walking wins. If you want strength and calorie burn, rucking is the move. Or combine them — interval walk with a light pack for the best of both worlds.
Rucking vs. Walking Yoga: Walking yoga blends mindful movement and flexibility work into your walk. Rucking is about load and intensity. They complement each other perfectly — ruck on your strength days, walking yoga on your recovery days.
Rucking vs. Power Walking: Power walking emphasizes speed and arm movement. Rucking keeps the pace moderate but adds weight. Rucking generally burns more calories at the same pace due to the external load.
Common Mistakes to Avoid
Going too heavy, too fast. This is the number one beginner mistake. Starting with 30+ pounds because it “doesn’t feel that heavy” in your living room will catch up with you at mile two. Start light. Ego-free.
Letting the pack sit too low. Weight should ride high on your back, close to your shoulder blades. A pack that sags to your lower back shifts your center of gravity and puts stress on your lumbar spine.
Skipping recovery. Rucking loads your joints and muscles more than regular walking. Allow 48-72 hours between sessions, especially in the first month. Active recovery like easy walking or walking yoga on off days is ideal.
Wearing the wrong shoes. Trail runners or hiking shoes with good ankle support work best. Avoid thin-soled shoes or sandals — you need cushioning and stability to handle the extra load.
Ignoring terrain. Research shows that terrain significantly affects energy expenditure during rucking. Loose sand can increase calorie burn by 50%, while trail surfaces add about 15%. Start on flat, paved surfaces and progress to trails as your fitness improves.

Frequently Asked Questions About Rucking
How many calories does rucking burn?
A 170-pound person rucking with a 25-pound pack at a brisk pace can expect to burn roughly 400-500 calories per hour. That’s about 2-3 times more than unloaded walking at the same speed. The exact number depends on your weight, pack weight, pace, and terrain. The Pandolf Equation, developed by U.S. Army researchers, is the gold standard for estimating rucking calorie expenditure.
Is rucking bad for your back?
Not when done correctly. The key is starting with an appropriate weight (10% of body weight), keeping the pack high and close to your back, and maintaining good posture throughout. Rucking actually strengthens your back and core muscles over time, which can reduce back pain. If you have a pre-existing back condition, start very light and consult with a fitness professional.
What should I carry in my rucking backpack?
Anything that adds weight safely. Ruck plates (flat weights made for backpacks) are ideal because they sit flush against your back. Budget alternatives include wrapped bricks, sandbags, water bottles, or heavy books. The key is placing the weight high in the pack, close to your shoulder blades, so it doesn’t swing or shift while you walk.
How often should beginners ruck?
Start with 2-3 sessions per week with at least one rest day between rucks. Your muscles, joints, and connective tissues need time to adapt to the added load. As your fitness improves over 4-6 weeks, you can increase frequency or add a longer weekend ruck.
Is rucking better than running?
They serve different purposes. Running is more time-efficient for pure cardiovascular fitness. Rucking builds more functional strength, burns comparable calories at lower speeds, and generates significantly less joint impact. Many people who find running uncomfortable discover that rucking gives them similar fitness benefits without the knee and ankle strain. For a well-rounded fitness routine, combining both — or mixing rucking with interval walking — covers all your bases.
Do I need a special rucking backpack?
Not to start. Any sturdy backpack with padded shoulder straps and a chest strap will work for loads under 20 pounds. As you progress to heavier weights or longer distances, a dedicated rucking backpack with a hip belt and internal frame will distribute the load better and protect your back. The most popular dedicated option is the GORUCK Rucker, though there are more affordable alternatives that work well for recreational rucking.
What is rucking and is it a good workout?
Rucking is the practice of walking with a weighted backpack, originally used in military training and now one of the fastest-growing fitness trends. It’s an excellent workout because it combines cardiovascular exercise with strength training in a single activity. Research from the Journal of Strength and Conditioning shows that rucking burns 2–3 times more calories than regular walking at the same pace — a 150-pound person carrying 20 pounds can burn roughly 400–500 calories per hour. Beyond calorie burn, rucking builds core strength, improves posture, and increases bone density through the added load. It’s also low-impact compared to running, making it joint-friendly for people of all fitness levels. Beginners should start with 10% of their body weight for 20–30 minutes and gradually increase. Rucking pairs well with other walking workouts like Nordic walking and power walking as part of a complete walking fitness program. Daily Burn’s guided walking workouts can help you build the base fitness needed for rucking.
