What if I said you could drop pounds, get better posture and build muscle with a workout that doesn't involve a single curl, push-up or press? Let's talk. To put weight on your back and go for a walk. More weight or more miles equals more results, more friends and more time together equals more fun. Sounds pretty simple, right? The word comes from what the military call "ruck sacks," or what you or I might call a backpack. ~ Berceste
