Rucking Burns 2-3x More Calories

The practice of rucking has deep military roots, dating back to at least the Roman Army, where legionaries were required to march over 20 miles in under five hours carrying more than 45 pounds of gear. This tradition continues in modern forces; for instance, to earn the U.S. Army's Expert Infantryman Badge, a soldier must complete a 12-mile ruck march with a pack weighing up to 70 pounds in under three hours. The transition to a civilian fitness trend was significantly boosted by former U.S. Army Special Forces member Jason McCarthy, who founded GORUCK in 2010 to bring military-grade gear and team-based endurance events to the public. Today, a large social infrastructure exists, with over 500 affiliated ruck clubs across the country creating a strong sense of community. These organized events, often led by decorated combat veterans, range from 5k races to challenges covering 40 or 50 miles over 24 hours. The focus is typically on camaraderie and teamwork rather than competition, with many events culminating in participants earning a patch. Beyond cardiovascular fitness, studies show rucking offers significant ancillary benefits. The weight-bearing nature of the exercise stimulates bone growth, which can increase bone mineral density and help prevent osteoporosis. It also engages core and back muscles to improve posture and can strengthen the muscles around the spine, potentially reducing back pain. Rucking is particularly effective for training in Heart Rate Zone 2, the optimal zone for maximizing fat burn. Additionally, the combination of being outdoors and exercising within a group has been shown to reduce stress and improve overall mental well-being.
