Bucket Brigade

Works best with 4 - 8 men. Line up at top of stairs (or large hill). One man on each stair shoulder-to-shoulder. Man on highest stair passes heavy object (i.e. 60lb sandbag, cinderblock, etc) down to next man, who passes it along the line. Once you hand off object, run down stairs to end of the line to receive object again. Once at bottom of stairs, repeat going back up.
