Rucking Gains Momentum as Cardio Alternative
Weighted walking with 10-30% bodyweight in a backpack is being hailed as underrated cardio that boosts endurance, strength, bone density, and calorie burn. Rucking burns 2-3x more calories than normal walking, with progression tips including adding distance, speed, or terrain difficulty. It's gaining traction among fitness enthusiasts looking for low-impact alternatives to running.
While its popularity in civilian fitness is recent, rucking's origins are deeply rooted in military history, a method used for centuries to build soldiers' endurance. Roman soldiers marched long distances with up to 60 pounds of gear, and the practice remains a cornerstone of modern military training to transport essentials like weapons and supplies. The term itself comes from "rucksack," the German word for backpack. A pivotal force in bringing rucking to the mainstream is GORUCK, a company founded in 2008 by former Green Beret Jason McCarthy. McCarthy's goal was to create durable rucksacks inspired by those used in U.S. Special Forces and to build a community around shared challenges. The company now organizes over 1,000 rucking events annually, from team-building challenges to endurance tests modeled after Special Forces training. The U.S. Army has specific standards for ruck marches, often requiring recruits to carry at least 35 pounds. For instance, to earn the Expert Infantryman Badge, soldiers must complete a 19km (approximately 12-mile) ruck march in under three hours with a pack weighing 31.75kgs (about 70 lbs). Elite units like the Army Rangers and Green Berets have even stricter requirements, needing to finish a 12-mile ruck in under 3 hours with a minimum of 35 pounds, though in practice they often carry more and aim for a faster pace. Compared to running, rucking presents a significantly lower risk of injury. Running can subject joints to forces 2-3 times your body weight with each step, leading to annual injury rates as high as 40-50%. Rucking, with its walking gait, keeps impact forces at a much lower 1.2-1.5 times body weight, resulting in a starkly lower annual injury rate of 10-15%. This lower impact doesn't mean a lower-quality workout. Rucking engages the entire body, including the upper back, core, and shoulders, to support the load, building functional strength. It also serves as an effective "Zone 2" cardio workout, elevating the heart rate to a level that maximizes fat burn while still allowing for conversation. The civilian rucking movement has grown into a global community with hundreds of local clubs and a wide variety of organized events. These range from themed 5K and 10K ruck races to endurance challenges and multi-day treks, often supporting charitable causes. This accessibility allows individuals of all fitness levels to participate, scaling the weight, distance, and terrain to their ability.
