Our read is that loaded carries, particularly rucking, are well supported as a beneficial activity for longevity.
Our read is that incorporating rucking into one's life can significantly increase activity levels and foster a more active lifestyle, promoting better posture and breathing by allowing the shoulders to remain back and enabling deep breaths, according to Peter Attia.
Peter Attia suggests that beginners should start with approximately 20 pounds for a couple of miles, and that persisting in rucking training leads to body adaptation and potential proactive increases in load.
However, Peter Attia also cautions that rucking with minimalist footwear can lead to foot problems, especially for individuals with hypermobile feet, and that using a hip belt can reduce stability and negatively impact posture and breathing.
Beginners to rucking should start with approximately 20 pounds for a couple of miles, according to Peter Attia. For safe rucking, especially for beginners, mastering correct movement form and removing ego regarding weight are crucial, as stated by Peter Attia. Peter Attia now prefers a supported boot with an 8mm drop for rucking to reduce injury risk, and recommends wearing the most supportive boot possible for high-stakes activities like hunting with heavy loads on difficult terrain. Using a sternum strap during heavy rucking can transfer load off the shoulders and improve blood flow, according to Peter Attia. Peter Attia prefers to minimize weight on his shoulders and maximize weight on his hips while rucking. Maintaining fitness for rucking training involves long rucks of varying weights and proactive foot care to prevent blisters, as noted by Peter Attia. Rocks or hotel gym dumbbells can be used as an alternative to rucking plates for weighted exercise while traveling, Peter Attia suggests. Alternating carrying methods can be beneficial for blood flow when carrying very heavy loads, according to Peter Attia.
Peter Attia warns that rucking with minimalist footwear can lead to foot problems, especially for individuals with hypermobile feet (1x). Peter Attia also notes that using a hip belt for rucking can reduce stability and negatively impact posture and breathing (1x). Additionally, Peter Attia cautions that faster and more pronounced galloping during rucking increases the risk of injury (1x).
Our verdict would change if new information emerged suggesting significant, widespread injury risks from properly executed loaded carries, or if the benefits were shown to be negligible compared to other forms of exercise.
