A smoke jumper has to be young and healthy to do the tough job of putting out fires in mountain lands. He must be able to carry heavy packs, sometimes more than a hundred pounds. He needs to know enough about getting along in the woods to find his way out of wild areas. He has to be able to climb tall trees, for sometimes th parachutes that carry his tools and food get caught in trees. New smoke jumpers go through a hard training school that prepares them for the rough work. They start early in the morning with exercises such as jumping jacks, push-ups, leg-lifts sit-ups and toe-touchers
