Does Rucking Build Muscle?

Rucking, a physical activity involving walking or hiking with a loaded backpack, has gained popularity recently as a versatile fitness exercise. Many individuals are drawn to rucking because of its potential to improve cardiovascular health, increase endurance, and burn calories.

However, a common question among fitness enthusiasts is whether rucking can effectively build muscle. This article will explore the benefits of rucking for muscle development and Does Rucking Build Muscle.

Understanding Rucking

Rucking involves walking or hiking while carrying a loaded backpack, commonly known as a rucksack. The backpack’s weight can vary depending on individual preference and fitness level, ranging from a few pounds to over fifty pounds. Initially utilized by the military for training, rucking has evolved into a popular exercise for people of all backgrounds seeking an effective and challenging workout.

The Benefits of Rucking

Rucking offers numerous benefits beyond traditional cardio exercises like running or cycling. It provides a full-body workout that engages various muscle groups while offering the advantages of spending time outdoors. Some key benefits of rucking include:

  • Improved cardiovascular health: Rucking elevates heart rate and promotes better circulation, enhancing cardiovascular endurance.
  • Increased calorie burn: Walking with a weighted backpack increases the intensity of the exercise, leading to higher calorie expenditure than regular walking.
  • Low impact: Unlike high-impact activities such as running, rucking places less stress on the joints, making it suitable for individuals with joint issues or those seeking a low-impact workout.
  • Mental well-being: Spending time in nature and engaging in physical activity has been linked to reduced stress levels and improved mental well-being.

Impact on Muscles

While rucking primarily targets the cardiovascular system, it also engages several major muscle groups. Let’s explore how rucking can contribute to muscle development:

4.1 Building Lower Body Strength

Rucking places a significant demand on the muscles of the lower body. The continuous load-bearing nature of the exercise stimulates the quadriceps, hamstrings, glutes, and calf muscles. As you walk or hike with a loaded backpack, these muscles stabilize your body and propel you forward, improving lower body strength and endurance.

4.2 Engaging Core Muscles

Maintaining an upright posture during rucking requires engagement of the core muscles, including the abdominals, obliques, and lower back. These muscles are crucial in stabilizing the spine and providing a solid foundation for movement. You can consistently challenge your core muscles during rucking to enhance their strength and stability over time.

4.3 Developing Back and Shoulder Muscles

The weight of the loaded backpack in rucking places a significant load on the upper body, particularly the back and shoulder muscles. These muscles, including the trapezius, rhomboids, and deltoids, are actively engaged in maintaining proper posture and supporting the backpack’s weight. Regular rucking can contribute to the development and toning of these muscles, leading to improved upper-body strength and stability.

Optimizing Rucking for Muscle Building

To maximize the muscle-building benefits of rucking, consider the following strategies:

5.1 Varying Terrain and Resistance

Incorporating diverse terrains such as hills, trails, or uneven surfaces during rucking adds an extra challenge and engages the muscles differently. It promotes muscle adaptation and helps prevent plateauing. Additionally, periodically increasing the backpack’s weight gradually introduces progressive resistance, further stimulating muscle growth.

5.2 Incorporating Interval Training

Integrating interval training into your rucking routine can enhance muscle development. Alternate between faster-paced walking or jogging periods and slower, more controlled walking to create an interval effect. This variation in intensity challenges the muscles and improves overall fitness.

5.3 Adding Weight Gradually

When starting with rucking, it is essential, to begin with a manageable weight and gradually increase it over time. This progressive overload principle stimulates muscle growth and minimizes the risk of injury. Start with a lighter backpack and gradually add weight as your strength and endurance improve.

5.4 Balancing Rucking with Strength Training

While rucking can contribute to muscle development, it is essential to supplement it with targeted strength training exercises. Combining rucking with exercises such as squats, lunges, and resistance training can provide a more comprehensive muscle-building stimulus.


Rucking is a versatile fitness activity that offers a range of benefits, including muscle development. By engaging various muscle groups and providing a challenging workout, rucking can contribute to the growth and strength of the lower body, core, back, and shoulder muscles. To optimize the muscle-building potential of rucking, it is crucial to vary terrain, incorporate interval training, add weight gradually, and balance it with targeted strength training exercises.
