Rucking, the act of walking or hiking with a weighted backpack, has long been a staple of military training, but it’s recently gained popularity as an effective workout for building muscle and losing fat. Unlike traditional cardio, rucking combines resistance and endurance, making it an efficient, low-impact option that anyone can try. In this article, we’ll explore how rucking can help you develop strength, improve endurance, and burn fat, while also benefiting muscle recovery and overall fitness—especially as we age.
What is Rucking?
Rucking has its roots in military training, where soldiers would carry heavy rucksacks over long distances to build strength and endurance. Today, rucking has evolved into a popular fitness practice that brings the benefits of resistance training and aerobic exercise into one dynamic activity. By simply adding weight to your backpack and walking at a moderate pace, you can turn a basic walk into a full-body workout.
The combination of weight and distance makes rucking more demanding than walking or hiking alone. The extra load increases the challenge on your muscles, particularly in the legs, back, shoulders, and core. Whether you’re navigating urban streets or challenging trails, rucking targets multiple muscle groups while giving you the cardiovascular benefits of aerobic exercise.
How Rucking Builds Muscle
When you ruck, you’re not just walking; you’re actively challenging your muscles with the added weight on your back. This resistance element is what turns rucking into a muscle-building activity. The weight forces your body to recruit muscles in your legs, core, and upper body to support the load and maintain posture. Here’s a breakdown of the primary muscles involved:
- Legs: The quads, hamstrings, and calves work hard to move and stabilize the body under load.
- Core and Lower Back: These muscles help stabilize the spine and maintain posture, particularly on uneven terrain.
- Shoulders and Upper Back: Carrying the ruck engages your shoulder and back muscles, improving posture and upper-body strength.
As you increase the weight in your rucksack over time, you create a progressive overload effect, similar to weight training. This ensures continuous muscle adaptation and growth. Rucking also complements traditional strength training, allowing you to build endurance in muscles that are typically hit during heavy lifting.
How Rucking Shreds Fat
One of the standout benefits of rucking is its ability to shred fat while preserving muscle. Rucking is more calorie-intensive than walking because of the added weight, and it engages multiple muscle groups at once. As a result, it burns more calories than traditional cardio like walking or jogging.
Rucking fits within a framework of combining resistance and aerobic activity, which is particularly effective for fat loss. It increases caloric expenditure while maintaining or even building muscle mass—essential for a leaner, more defined physique.
Additionally, rucking has a higher post-exercise oxygen consumption (EPOC) than regular walking or running, meaning your body continues to burn calories at an elevated rate even after your workout ends. This makes rucking a great tool for those aiming to shed fat without sacrificing muscle mass.
Rucking for Recovery
Rucking serves as an excellent recovery tool, thanks to its low-intensity aerobic nature. The combination of steady walking and added weight enhances circulation throughout the body, which helps deliver oxygen-rich blood to the muscles, aiding in recovery. Increased blood flow helps reduce muscle soreness, clears metabolic waste, and promotes faster healing after strenuous workouts.
Unlike high-impact activities such as running, rucking is easier on the joints and muscles, allowing you to stay active while promoting recovery. This makes it an ideal option between more intense strength training sessions, helping you maintain fitness without overstressing your body.
Incorporating rucking into your weekly routine can help you stay active on recovery days, giving your muscles time to heal while keeping your metabolism elevated.
Rucking for Endurance
Rucking is a fantastic way to build muscular endurance, particularly in the slow-twitch muscle fibers that are essential for sustaining prolonged activity. These fibers are responsible for helping you maintain consistent movement over long periods, making them crucial for activities that require stamina, like hiking or endurance sports.
Loaded walking (rucking) is particularly effective at targeting these fibers in the legs, back, and core, as the added weight forces your body to work harder to maintain stability and forward motion. Over time, this leads to greater endurance and improved resistance to fatigue.
This is especially beneficial for aging adults, as endurance and muscle function tend to decline with age. Rucking helps counteract this by promoting the growth and maintenance of slow-twitch muscle fibers, keeping you more resilient and physically capable in day-to-day activities. By building both muscular and cardiovascular endurance through rucking, you can improve overall stamina, maintain functional strength, and reduce the risk of injury as you age.
Rucking as a Full-Body Workout
Rucking is not just a leg workout—it’s a full-body challenge that engages nearly every major muscle group. With the extra weight on your back, your body must work harder to maintain balance and stability, which recruits muscles in your core, shoulders, and upper back in addition to your legs.
Muscles Worked During Rucking:
- Legs: The primary movers during rucking, particularly the quads, hamstrings, glutes, and calves.
- Core and Lower Back: Stabilizing the added weight requires constant engagement of the core and lower back.
- Shoulders and Traps: Carrying a ruck engages your upper back and shoulders, improving posture and upper-body endurance.
To maximize the benefits, it’s important to focus on form. Keep your posture upright, shoulders back, and engage your core to prevent strain on your lower back. Start with a moderate weight and work your way up to heavier loads as you build strength and endurance.
Rucking for Beginners vs. Advanced Ruckers
Getting Started
If you’re new to rucking, it’s best to start light and focus on form. A good starting point is 10-20% of your body weight in your ruck. Begin with short distances, around 1-2 miles, and gradually increase either the weight or the distance as your body adapts.
For Advanced Ruckers
As you become more experienced, you can add more weight, tackle steeper inclines, or incorporate intervals of faster walking or even jogging to increase intensity. Advanced ruckers can also experiment with rough terrain or combine rucking with bodyweight exercises like lunges, push-ups, and squats to further challenge their muscles.
Combining Rucking with Nutrition for Optimal Results
To maximize the muscle-building and fat-burning benefits of rucking, it’s important to fuel your body properly. For fat loss, maintaining a caloric deficit is key. However, you’ll also want to prioritize protein intake to support muscle recovery and growth.
Pre- and Post-Ruck Nutrition:
- Before a Ruck: Eat a meal rich in carbohydrates and protein about 1-2 hours before your session to ensure you have enough energy.
- After a Ruck: Focus on protein to aid muscle repair, along with some carbohydrates to replenish energy stores.
Hydration is also critical, especially for longer rucks. Drink water regularly during your ruck and consider carrying a hydration pack if you’re going for longer sessions.
Benefits of Rucking Beyond Muscle and Fat Loss
In addition to muscle building and fat shredding, rucking offers several other benefits:
- Mental Toughness: Rucking challenges your endurance and mental resilience. The discipline required to carry weight over distance can improve mental toughness.
- Functional Fitness: The strength and endurance built through rucking carry over into everyday activities, making tasks like carrying groceries or climbing stairs easier.
- Social Aspect: Rucking can be done solo or in groups, making it a great social activity. Many communities have rucking groups that motivate and support each other.
