Below you can find a recent article from the London Times. I was used as a source for the article that discusses "Rucking, Ruck Marching, or Tabbing as the Brits call it" as a popular new fitness trend. Rucking is unique to the military, with the closest civilian version of this activity being backpacking. The loads that are generally carried in the military far exceed the loads commonly carried while backpacking. I do believe rucking can be a great workout for almost anyone.
