Is Rucking Resistance Training? Unpacking the Benefits and Limitations
Rucking, the act of walking or hiking with a weighted backpack, has surged in popularity as a versatile fitness activity. Often touted for its blend of cardio and strength benefits, a key question arises: Is rucking truly resistance training? This blog post delves into the science behind rucking, exploring its place within the spectrum of resistance training and how it can effectively contribute to your fitness goals.
Introduction: The Rise of Rucking and the Resistance Question
From military origins to mainstream fitness circles, rucking has gained traction for its simplicity and effectiveness. It requires minimal equipment – a backpack and some weight – and can be incorporated into everyday routines. Many fitness enthusiasts and articles promote rucking as a form of resistance training, highlighting its ability to build muscle and strength. But is this classification accurate? To answer this, we first need to understand what resistance training truly entails.
Defining Resistance Training: More Than Just Lifting Weights
Resistance training, also known as strength training or weight training, is any exercise that causes your muscles to contract against an external resistance. This resistance can come from various sources, including:
- Free weights: Barbells, dumbbells, kettlebells
- Weight machines: Cable machines, leg press machines
- Resistance bands: Elastic bands of varying resistance
- Bodyweight: Push-ups, squats, planks
The primary goal of resistance training is to overload the muscles, prompting them to adapt and become stronger, more powerful, and potentially larger (hypertrophy). The American College of Sports Medicine (ACSM) recommends resistance training at least two days per week for all major muscle groups to improve overall health and fitness.
Benefits of resistance training are well-documented and include:
- Increased muscle strength and power
- Improved muscle mass and metabolism
- Enhanced bone density
- Reduced risk of injury
- Improved functional fitness for daily activities
- Better glucose control and insulin sensitivity
Rucking Explained: Weight on Your Back, Benefits in Your Stride
Rucking, at its core, is walking or hiking with added weight, typically in a backpack or “rucksack.” Originating from military training, it’s designed to build endurance, strength, and mental fortitude for soldiers who frequently carry heavy loads over long distances. In civilian fitness, rucking offers a accessible way to:
- Improve cardiovascular fitness: Rucking elevates your heart rate, providing a good cardio workout.
- Increase calorie expenditure: Carrying extra weight burns more calories than walking without weight.
- Build muscular endurance: Sustained weight-bearing activity challenges muscles over time.
- Enhance posture and core strength: Maintaining proper posture while rucking engages core muscles.
- Enjoy low-impact exercise: Compared to running or jumping, rucking is gentler on the joints.
To ruck effectively, start with a comfortable backpack and gradually increase the weight. Begin with shorter distances and lighter loads, progressing as your fitness improves. Proper form is crucial to prevent injury: maintain good posture, engage your core, and choose appropriate footwear. Organizations like GORUCK, popular in the rucking community, advocate for starting with 10-20% of your bodyweight and adjusting based on fitness level and goals.
The Case for Rucking as Resistance Training: Where the Claims Hold Weight
There’s a valid argument to be made for considering rucking as a form of resistance training. Here’s why:
- External Load as Resistance: The added weight in the backpack acts as external resistance against gravity. Your muscles must work harder to move your body and the additional load.
- Muscle Engagement: Rucking engages numerous muscle groups, particularly in the lower body (legs, glutes), core, and back, to stabilize and propel the weighted load. This constant muscle activation contributes to muscular endurance and strength gains to some extent.
- Increased Intensity Compared to Unweighted Walking: Rucking significantly increases the intensity of walking. This higher intensity can lead to adaptations in muscle strength and endurance over time, especially for individuals new to exercise or those seeking a low-impact strength-building activity.
- Functional Strength Development: Rucking builds functional strength applicable to real-world activities. Carrying weight while walking simulates tasks like carrying groceries, hiking with a pack, or even everyday movements with increased resilience.
As The New York Times highlighted, rucking “is a great way to combine strength training and cardio without setting foot inside a gym.” This statement underscores the integrated nature of rucking, offering both cardiovascular and resistance training benefits in one activity.
The Limitations: Why Rucking Isn’t Just Resistance Training
While rucking offers resistance training benefits, it’s crucial to acknowledge its limitations compared to traditional, targeted resistance training methods. Rucking, on its own, is not a comprehensive resistance training program for several reasons:
- Limited Muscle Groups Targeted for Hypertrophy: Rucking primarily emphasizes muscular endurance and strength in the legs, core, and back. It’s less effective for targeting upper body muscle hypertrophy (muscle growth) compared to exercises like bench presses, pull-ups, or overhead presses.
- Progressive Overload Challenges for Strength Gains: While you can increase the weight in your ruck, the scope for progressive overload specifically for strength development is limited. Continuously adding weight to rucking can become unsustainable and may increase the risk of injury. Traditional resistance training allows for more precise and incremental increases in resistance, sets, and reps to drive strength gains.
- Specificity of Training: Resistance training is often tailored to specific fitness goals and movement patterns. Rucking is a general, compound movement. For athletes or individuals with specific strength and power goals (e.g., improving vertical jump, maximal lifting strength), rucking alone won’t provide the targeted stimulus needed for optimal results.
- Less Efficient for Maximal Strength Development: To maximize strength gains, lower rep ranges with heavier weights are generally more effective. Rucking, by nature, is a higher repetition activity (steps taken) with a submaximal load. While it builds strength endurance, it’s less efficient for developing maximal strength compared to heavy weightlifting.
Therefore, while rucking *is* a form of resistance training, it’s more accurately classified as a low-to-moderate intensity, endurance-focused resistance activity. It shouldn’t be considered a replacement for a well-rounded resistance training program if your primary goals are significant muscle hypertrophy or maximal strength gains across all major muscle groups.
The Power of Synergy: Combining Rucking with Targeted Resistance Training
The most effective approach to fitness often involves a balanced strategy. Instead of viewing rucking and traditional resistance training as mutually exclusive, consider their synergistic potential. Combining rucking with targeted resistance exercises can create a comprehensive fitness regimen that maximizes benefits:
- Rucking for Cardio and Endurance Base: Use rucking as your primary cardiovascular activity and to build a solid foundation of lower body and core endurance. Incorporate rucking 2-3 times per week for 30-60 minutes.
- Targeted Resistance Training for Strength and Hypertrophy: Supplement rucking with 2-3 sessions of traditional resistance training per week. Focus on exercises that target major muscle groups not optimally stimulated by rucking, particularly the upper body (chest, shoulders, arms) and potentially legs with heavier loads and variations (e.g., squats, deadlifts, presses, rows).
- Example Weekly Schedule:
- Monday: Rucking (45 minutes)
- Tuesday: Upper Body Resistance Training
- Wednesday: Active Recovery (Yoga, Stretching)
- Thursday: Rucking (60 minutes)
- Friday: Lower Body Resistance Training
- Weekend: Rest or longer ruck/hike for enjoyment
- Progressive Overload in Both Domains: Gradually increase the weight and distance in your rucks. In your resistance training sessions, focus on progressive overload by increasing weight, reps, sets, or exercise difficulty over time.
By strategically combining rucking and traditional resistance training, you can reap the benefits of both: enhanced cardiovascular fitness, muscular endurance, and significant strength and muscle growth. This balanced approach is ideal for overall fitness, functional strength, and long-term health.
Key Takeaways: Rucking’s Role in Your Fitness Journey
