Biomechanist Katy Bowman and biologist Jeannette Loram talk about rucking—walking with weight on your back—and other modes of carrying. They touch on the evolutionary history of carrying, carrying in modern Hunter Gatherer populations, rucking in the military and the benefits of fitness rucking.
Jeannette and Katy focus on the challenges associated with rucking particularly pain and discomfort. They explain how different body adjustments—like leaning forward, arching the back, or shifting the hips forward—are responses to offset the backward-pulling force of a heavy load. These shifts help accommodate the extra mass, but if a single adjustment is done repetitively or without muscular support through the core, pain can be the result.
Listen in to discover a more varied and mindful approach to managing your ruck; your low back will thank you!
