This exercise is very effective at improving muscular endurance in the forearms, shoulders, back, and legs. This exercise is very flexible and can be done in a gym with kettlebells, dumbbells, or plate weights. In a home/improvised setting it can be done with water jugs, sandbags, or heavy bags. The important part is to maintain posture while you walk with these weights. Shoulders should not be allowed to drop. If this is happening, decrease the weight or the distance that you are doing.
